Lithographically-Patterned Quantum Dot Structures for Infrared Detection

9906247TsuiQuantum Well红外探测器(QWIP)具有重要的科学和技术意义。如果将一维(ID)量子线的横向尺寸缩减为OD量子点，则QWIP的性能将得到显著提高。这项研究的目标是开发图案化量子点(PQD)结构，探索PQD的基本物理原理，开发PQD的纳米修饰技术(如纳米压痕和分子束外延)，并研究PQD的红外检测。这项拟议的研究是基于三位专家的独特组合，他们分别是量子井物理(徐教授)、红外光电探测器(崔博士)和纳米制造(周教授)。~研究结果将对图案化量子点、量子井红外光电探测器、量子井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.***
