15955 近年来液晶显示屏面临来自AMOLED的挑战,但液晶显示仍然是目前最主流的显示技术。 Recently,LCD has faced the realistic challenge from AMOLED,but LCD is still the most mainstream display technology.

15958 为了使基于AlGaN外延材料的深紫外发光二极管(DUV LED)的内量子效率(IQE)随驱动电流的增大而降低的幅度减小,有助于DUV LED在一个较大的驱动电流区间可以稳定地工作,提出并研究具有Al组分V型渐变P型电子阻挡层(P-EBL)结构的DUV LED。通过Crosslight APSYS软件对常规P型电子阻挡层(P-EBL)和Al组分V型渐变P-EBL结构DUV LED的能带、极化体电荷、电子电流、空穴浓度、内量子效率、输出功率和自发辐射光谱进行了数值研究。 In order to reduce the rate at which the internal quantum efficiency(IQE)of the AlGaN-based deep ultraviolet light-emitting diode(DUV LED)decreased with the increase of the driving current,it was desired that the DUV LED could work stably in a larger driving current range. A DUV LED with an Al composition V-graded P-type electron blocking layer(P-EBL)structure was proposed and studied. Based on the Crosslight APSYS software,the energy band,polarization induced bulk charges,electron current,hole concentration,internal quantum efficiency,output power and emission spectrum of conventional P-type electron blocking layer(P-EBL)and Al composition Vtype gradient P-EBL structure DUV LED were numerically studied.
15959 结果表明,在260 mA电流注入时,相比常规P-EBL结构,Al组分V型渐变P-EBL结构DUV LED的效率降低的幅度减小了5.86%,改善了DUV LED输出性能。根据数值模拟和分析,器件输出性能改善的原因是Al组分三角形渐变P-EBL沿生长方向产生的极化体电荷,抵消P-EBL与最后一个量子垒层异质结界面处存在的极化面电荷,从而减小了界面处的极化电场。 The results showed that at injection current of 260 mA,compared with the conventional P-EBL structure,the efficiency drop of the Al composition V-gradient P-EBL structure DUV LED was reduced by 5.86%,improving the output performance of the DUV LED. According to numerical simulation analysis,the reason for the improvement of the device output performance was the decrease of the polarization induced bulk charges generated by the triangular gradient P-EBL of Al composition along the growth direction,which could offset the interface polarization charge and reduce the polarization electric field generated at the heterojunction interface between the P-EBL and the last quantum barrier layer.

15964 聚光三结砷化镓电池具有优良的温度特性与光照特性,温度系数小、光吸收系数大且抗辐射能力强,若能用于激光无线能量传输系统则可以提高系统光电效率和功率密度,此时发射端背景光需要使用三波长激光混合入射。 The concentrating triple junction GaAs battery has excellent temperature characteristics and light characteristics,small temperature coefficient,large light absorption coefficient and strong radiation resistance. When it is used in laser wireless power transmission systems,it could improve the photoelectric efficiency and power density of the system,and meanwhile the background light at the emitting end needs to be mixed with three-wavelength lasers.
