We report high-efficiency red organic light-emitting diodes (OLEDs) and color-tunable white OLEDs using a novel red phosphorescent material. The transient PL decay measurement indicates that this red emitter exhibits a very-short lifetime, which is dependent on dopant concentration. Based on an optimized dopant concentration, we have fabricated a high-efficiency red electroluminescent device with a maximum external quantum efficiency (EQE) up to ηEQE= 22.6%. Furthermore, the color-tunable white organic light-emitting diodes by introducing this red dopant have been fabricated, in which CIE chromaticity coordinates follows the Planckian locus in warmer-color regions.

With the rapid development of automotive electronics and near-eye displays, more stringent requirements have appeared for the heterogeneous integration technology of Micro-LED. Copper pillar bumps, which offer enhanced electrical conductivity, thermal conductivity, and mechanical properties, can meet the demands for higher density and smaller size packaging in Micro-LED array applications. In Micro-LED system integration, bonding plays a critical role as the bonding conditions significantly influence the performance and reliability of Micro-LED. Consequently, it is essential to investigate the effects of bonding conditions on Micro-LED devices to ensure optimal performance and reliability of copper pillar bumps. A model with copper pillar bumps and Micro-LED chips was presented with a bonding simulation and parameter analysis performed in this paper. The finite element method was utilized to examine the thermal-mechanical coupling of one quarter of a 5×5 Micro-LED array model in this paper. The stress and deformation of the bumps during the bonding process and the effects of bonding conditions on the stress and deformation of the bumps was investigates. ©2024 IEEE.

In modern electronic devices, linear regulator is increasingly important. Modules in a system may require different supply voltages, and the system always has only one supply. So a regulator will be needed. This paper describes a voltage regulator which can solve the problem above. Different types of vehicles has different battery voltage, the regulator described in this paper can convert the input voltage with a big range (10v-40v) to 3.3v. The output can supply other modules in a system of automotive electronics. The experimental results show that all main expectations are achieved. © 2011 IEEE.

With the development of IoT and AI technologies, brain-like synaptic devices with precise weight modulation of synaptic plasticity and controllable preparation are of great significance for developing neuromorphic computing and intelligent sensing technologies. In this paper, we design a series of side-gate electrolyte transistors with varying gate-channel distances and systematically examine the structural design effect on synaptic weight modulation. A synaptic transistor device with an ultra-low subthreshold swing of 89.8 mV/dec has been successfully achieved by optimizing the gate-channel design. Additionally, Further characterizations of the short-term synaptic plasticity and long-term synaptic plasticity of synaptic transistors uncover the flexible modulation of the gate-channel distance-dependent synaptic weight gain behaviors, which span from as low as 6.1 to as high as 87.5 under 50 successive stimuli. The results of this work provide a reliable solution for the design and preparation of high-performance synaptic devices and lay the foundation for high-precision neural networks and intelligent sensing technologies. ©2024 IEEE.

Hologram calculating of 3D object has different computation methods. This paper mainly introduces the principle of slice-based Fresnel diffraction and point-based with Fresnel zone plate (FZP), and analyzes the imaging quality of the numerical reconstruction results by using our proposed methods. The reconstruction results show that Fresnel diffraction method is better in imaging quality. © OSA 2017.

Pan Tao Ti Hsueh Pao/Chinese Journal of Semiconductors 2008年第4期29卷 650-654页

作者： Bai, Yu Khizar-Ul-Haq Khan, M.A. Jiang, Xueyin Zhang, Zhilin Department of Materials Science Shanghai University Shanghai 201800 China Key Laboratory of Advanced Display and System Application Shanghai University Shanghai 200072 China

An organic thin-film transistor (OTFT) with an OTS/SiO2 bilayer gate insulator and a MoO3/Al electrode configuration between gate insulator and source/drain electrodes has been investigated. A thermally grown SiO2 layer is used as the OTFT gate dielectric and copper phthalocyanine (CuPc) is used as an active layer. This 0TS/SiO2 bilayer gate insulator configuration increases the field-effect mobility, reduces the threshold voltage, and improves the on/off ratio simultaneously. The device with a MoO3/Al electrode has shown similar Ids compared to the device with an Au electrode at the same gate voltage. Our results indicate that using a double-layer of electrodes and a double-layer of insulators is an effective way to improve OTFT performance.

In this paper, the Sr-doped In2O3 thin film is fabricated by aqueous route and the stability of InSrO thin film transistor under negative bias illumination stress (NBIS) is investigated. It is found that Sr can effectively improve the stability of In2O3 TFTs under NBIS, which is due to the reduction of oxygen vacancies. The XPS measurement is tested to analyze the variation of oxygen vacancy concentration. The density of states is calculated to further confirm the decrease of total trap state caused by Sr doping. © 2019, John Wiley and Sons Inc. All rights reserved.
