Abstract ：
以超高密度Cu/Sn微凸点和Cu/SnAg微凸点为研究对象,采用COMSOL软件建立仿真模型,研究了不同焊料凸点高度对键合可靠性的影响;采用电镀法制备Cu/Sn凸点阵列和Cu/SnAg凸点阵列,重点对界面处金属间化合物(Intermetallic compounds,IMC)进行研究.结果表明,Cu/SnAg凸点高度的增加有利于降低凸点键合界面应力,从而提高芯片键合可靠性.金属凸点尺寸越小,界面处金属间化合物生长越快,空洞数量越多.雾锡凸点的晶粒尺寸大于亮锡凸点,而且晶界数量较少,使得凸点界面上IMC的生长速度较慢.因此,雾锡凸点能够有效减少凸点界面空洞的形成,SnAg合金替代纯锡材料可以进一步减少凸点界面空洞的形成.通过优化工艺条件,成功制备出点间距为8 μm,像素阵列为1 920×1 080的超高密度Cu/SnAg金属凸点.

Abstract ：
Power grid is an indispensable infrastructure in modern society, in order to ensure the normal operation of the grid, online non-contact monitoring of high-voltage lines is essential. In this work, a 'capacitor-laser diode (LD)-capacitor' structure, namely, laser diode in capacitors (LDIC), that can be used for non-contact monitoring of high-voltage (HV) line status by directly transferring the status information of the HV line to modulated laser pulses is proposed. The proposed LDIC can accurately extract the real-time voltage changes on the HV line with an accuracy level of 0.959%. Because the LDIC is sensitive to high-frequency electromagnetic field, the LDIC is successfully utilised to detect the external electromagnetic interference (EMI) to obtain the intensity and frequency of the external EMI. Additionally, the amplitude and frequency of the HV line vibration can be accurately monitored by using the LDIC. For the third-order curve fitting of vibration amplitude, the average error is only 0.00867, and the average error of linear fitting of vibration frequency is as low as 0.00655. This work provides a novel approach for the online monitoring of the HV line status and a new supplement for the development of power grid technology.

Abstract ：
Amorphous gallium oxide (a-Ga2O3) has a low carrier concentration and limited mobility, which constrains its application in neuromorphic computing. In this study, Zn-doped Ga2O3 (ZGO) artificial synaptic devices were fabricated under oxygen-free conditions using radio-frequency magnetron sputtering (RFMS). Compared to undoped Ga2O3, the ZGO device exhibited a 106-fold increase in excitatory postsynaptic current under 254 nm illumination, with the response intensity positively correlated with the optical pulse parameters. Under light pulse modulation, the devices demonstrated dynamic behavior transitioning from short-term plasticity to long-term plasticity, including paired-pulse facilitation and the learning-forgetting-relearning process. Furthermore, the electrical and optical energy consumption of synaptic events are as low as 28 fJ and 2 nJ, respectively. The mechanism analysis indicates that the persistent photoconductivity effect in the ZGO thin film is attributed to the abundant oxygen vacancies. A multi-layer perceptron simulation based on ZGO devices achieved a 90.74% accuracy in handwritten digit recognition, and maintained 76.18% accuracy even with 50% noise. Zn doping provides a new material design approach for Ga2O3-based neuromorphic devices, demonstrating potential for future applications in neuromorphic computing.

Abstract ：
As Micro-LED sizes shrink, luminescence efficiency drops significantly due to sidewall damage from plasma etching. This study introduces a precision-selective ion implantation (PSII) strategy to boost external quantum efficiency (EQE) and brightness of Micro-LED at high current density, vital for applications like augmented reality (AR) and optical communication, instead of relying on sidewall passivation for low current density efficiency. PSII's effects is systematically evaluated on electrical isolation and photoelectric properties. Results demonstrate that Micro/Nano-LED arrays with a pixel density up to 25,400 ppi are achieved through the PSII strategy. Turn-off leakage current is reduced, with improved carrier injection efficiency, EQE, and luminance. At 10,000 A cm- 2, EQE and brightness increased by approximate to 30% and approximate to 25%, respectively. Moreover, lattice damage induced by ion bombardment enhanced UV and blue light absorption while suppressing visible emission, which benefits photodetectors (PDs). Demonstrations in AR displays, optical communication systems, and UV PDs showed superior performance compared to etching-based methods. The modulation bandwidth reached 131.2 MHz, a 30% improvement, and PD photocurrent increased by approximate to 90%. This PSII-based pixelation strategy enables high-brightness Micro-LED displays with significant potential for multifunctional integrated applications, offering a robust alternative to traditional etching processes for advanced optoelectronic devices.

Abstract ：
The near-eye display device, based on naked eye 3D display technology, holds significant potential as a next generation display for the metauniverse, offering a new way to interact with digital content. Integral imaging (II) naked eye 3D display, with its advantages, such as full parallax, full color, and good compatibility, shows great commercial promise. Depth of field (DoF) is a critical factor for creating immersive 3D experiences, allowing viewers to engage deeply with the content. This paper proposes a triple-focal microlens array (TF-MLA) with a honeycomb arrangement to simultaneously improve DoF and resolution for II 3D display. Firstly, the imaging principles of II 3D display based on the TF-MLA was analyze and the DoF formula was derived. Then the TracePro optical simulation software was applied to simulate the light field reconstruction process of the TF-MLA II system to investigate the effects of object distance and image distance on display performance. Results show that traditional II system has only one central depth plane, while the TF-MLA create three distinct central depth planes, enabling the reconstruction of 3D objects at three different depths simultaneously. The DoF of the TF-MLA II system is 3.5 times that of the traditional II system. © 2025, John Wiley and Sons Inc. All rights reserved.

Abstract ：
Developing micro- and nano-scaled full-color pixelation is crucial for advancing future display technologies. Transmission metasurface structural color (TMSC) shows promise for integrated displays due to its high resolution and stability. However, improving the color gamut and tunability of TMSC remains a challenge. In this study, we modified the conventional single-metal metagrating (Ag-Al2O3) by replacing the Ag grating layer with an Al-Al2O3-Ag hybrid grating layer. This novel TMSC based on the mixed metagrating achieves unique transmission spectra under TM polarization light, featuring a single peak with minimal sidebands, and near-zero transmission under TE polarization light. This design enables ultra-high color purity and switchable colors through polarization adjustment. The metagrating effectively blocks transmission sidebands by leveraging interactions between the top Al grating layer and the Al2O3 sandwich grating layer. Under TM polarization light, the TMSC using this mixed metagrating covers an expansive color gamut-173% sRGB space and 124% Adobe RGB space-nearly achieving full hue and high purity. Conversely, under TE polarization light, the TMSC based on the mixed metagrating achieves near-zero transmission, ideal for a perfect dark mode. Moreover, the proposed TMSC design allows for full hue adjustment of individual pixels by varying the incident angle under TM polarization light. Under TE polarization light, the dark mode remains stable regardless of incident angle variations. The metagrating holds significant potential for applications in displays, high-density information storage, optical encryption, and beyond.

Abstract ：
The fabrication of uniform metal bump arrays with submicron-sized diameters is crucial for achieving Micro-LED displays with ultra-high pixel density. This study presents a fabrication strategy that utilizes an undercut sacrificial layer in the lift-off process to achieve fine-pitched metal bump arrays. The influences of sacrificial layer thickness and developing time on the undercut degree, as well as their effects on the morphology and dimensional consistency of bumps, are investigated. It is observed that increasing the developing time leads to a higher degree of undercut, not only facilitating the lift-off of the sacrificial layer but also resulting in an increased base radius of the metal bumps. By optimizing process parameters, we successfully achieved Au bump arrays with a base radius around 0.99 mu m, top radius around 0.3 mu m, and a pitch size of 1.4 mu m, exhibiting height nonuniformity below 5%. This fabrication strategy for uniform metal bump arrays with ultra-high density will greatly contribute to advancing Micro-LED technology towards high definition and high brightness.

Abstract ：
Microlight-emitting diodes (Micro-LEDs) offer numerous unique advantages in terms of materials, devices, technologies, and process applications. To enable control of LEDs with low current input, a heterojunction integrated light-emitting transistor (H-LET) device is proposed. By vertically integrating a heterojunction bipolar transistor (HBT) with a Micro-LED, a multifunctional optoelectronic device capable of light emission, modulation, and driving functions is achieved. The structure incorporates wide-bandgap aluminum gallium nitride (AlGaN) material into the emission region, forming a heterojunction with GaN. This significantly enhances electron injection efficiency and current gain. Under low current drive, the H-LET device achieves a current gain of up to 650. This results in superior current regulation and high-frequency response compared to homojunction light-emitting transistors. The H-LET shows significant potential for applications in smart lighting, high-definition displays, radio frequency systems, and high-speed communication. © 2025 Wiley-VCH GmbH.

Abstract ：
With the development of the economy and science, information technology has become increasingly integrated into modern life, making information encryption crucial. The molecular arrangement of cholesteric liquid crystals (CLCs) exhibits a unique helical structure, which provides excellent bistability. This molecular arrangement can be changed under the action of an electric field, consequently changing the transmittance of light. The triboelectric nanogenerator (TENG) is a novel energy-harvesting system that can convert mechanical energy into electrical energy to power small devices. In this research, the optical properties of a CLC and the energy independence of a TENG were utilized to support an information encryption system for data security, and in this paper, a feather-based, horizontal, sliding TENG that offers a voltage range adjustable between 30 and 300 V to facilitate switching between the planar and the focal cone textures of CLCs is proposed. Moreover, when a self-powered CLC was combined with a convolutional neural network, the accuracy of message transmission reached more than 98 %; thus, a message encryption transmission system with good portability and low cost was realized.
