Lithographically-Patterned Quantum Dot Structures for Infrared Detection

Tsui量子阱红外探测器（QWIPs）具有重要的科学和技术意义。如果将一维量子线的横向尺寸减小到OD量子点，则QWIPs的性能可以得到显著改善。本研究的目标是发展图案化量子点结构，探索量子点的基本物理，发展量子点的纳米图案化技术（如纳米压印和分子束外延），并研究量子点的红外探测。拟议的研究是基于量子阱物理学（徐教授），红外光电探测器（崔博士）和纳米纤维（周教授）三位专家的独特组合。研究结果将对图案化量子点，量子阱红外光电探测器，量子阱物理和应用以及纳米压印光刻应用产生重大影响。

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.***
