Lithographically-Patterned Quantum Dot Structures for Infrared Detection

量子阱红外探测器（qwip）具有重要的科学和技术意义。如果将一维（ID）量子线的横向尺寸减小到OD量子点，则可以大大提高qwip的性能。本课题的研究目标是建立量子点结构，探索量子点的基本物理特性，开发量子点的纳米图像化技术（如纳米压印和MBE），并研究量子点的红外探测。提出的研究是基于量子阱物理学（Tsui教授），红外光电探测器（Choi博士）和纳米制造（Chou教授）的三位专家的独特组合。~本研究成果将对量子点图像化、量子阱红外探测器、量子阱物理与应用、纳米压印光刻等领域产生重大影响

9906247TsuiQuantum well infrared photodetectors (QWIPs) are of great scientific as well as technological importance. The QWIPs performance can be drastically improved, if the lateral dimension of a one-dimensional (ID) quantum wire is reduced to a OD quantum dot. The goal of the proposed research is to develop patterned quantum dot (PQD) structures, to explore the fundamental physics in PQDs, to develop nanopatterning technology for PQDs (such as nanoimprint and MBE), and to investigate the infrared detection of PQDs. The proposed research is based on a unique combination of three experts in quantum well physics (Prof. Tsui), infrared photodetectors (Dr. Choi), and nanofabrication (Prof. Chou).~ The outcome of the research will have significant impact to patterned quantum dots, quantum well infrared photodetectors, quantum well physics and applications, and nanoimprint lithography applications.***
