Improved Materials for Wide Bandgap II-VI Visible Emitters and Devices

项目编号：ECS-9707213项目负责人：Maria Tamargo标题：改进的II-VI类宽禁带可见发射体和器件材料分析：本研究将研究一类II-VI类材料在III-V基板上生长的可见发射体的优化设计。所研究的II-VI材料体系为MgZnCdSe， III-V衬底为InP。该系统的一个强大优势是薄膜和衬底之间的良好晶格匹配，这将增加器件的寿命和可靠性。新的研究将包括调查(1)界面终止或“封盖”方案，以减少界面上的缺陷，(2)高p型掺杂的Te掺入和(3)晶格硬化的Be掺入。这种系统的重要应用包括蓝绿色发光二极管和激光二极管。

Proposal Number: ECS-9707213 Principal Investigator: Maria Tamargo Title: Improved materials for wide bandgap II-VI visible emitters and devices Analysis: In this research, the optimization of a class of II-VI materials for the design of visible emitters grown on III-V substrates will be investigated. The II-VI materials system under investigation is MgZnCdSe and the III-V substrate is InP. A strong advantage of the proposed system is the good lattice match between the film and the substrate which should result increased device lifetime and reliability. The new research will include investigations into (1) an interface termination or "capping" scheme for reduction of defects at the interface, (2) Te incorporation for high p-type doping and (3) Be incorporation for lattice hardening. Important applications of such systems include blue-green light emitting diodes, and laser diodes.
