第73期：Quantum well infrared photodetector array development and applications
2008-05-16
德国离子束物理和材料研究所的Harald Schneider博士应我所马文全研究员的邀请于4月2日上午来我所学术交流，并在“半导体科学技术论坛”上作第73期讲座，望广大科研人员及研究生积极参加!
报告题目: Quantum well infrared photodetector array development and applications
时间: 2008年4月2日(星期三) 上午 9:00
地点: 中科院半导体研究所学术会议中心
报告人: Harald Schneider(Institute of Ion-Beam Physics and Materials Research, Dresden, Germany)
Abstract:Quantum well infrared photodetector (QWIP) technology has opened up new opportunities to realize focal plane arrays (FPA) for high-performance thermal imaging <1>. High thermal and spatial resolution, low 1/f noise, low fixed-pattern noise, and high pixel operability makes QWIP FPAs appropriate for many applications. Due to their narrow absorption bands with relative spectral widths of the order of 10%, QWIPs are particularly suitable for thermal imaging applications involving several atmospheric transmission bands or several colors within the same band. In this talk, I will report on the development of QWIP structures optimized for thermal imaging applications and on the performance of QWIP cameras which were jointly realized by the Fraunhofer-Institute for Applied Solid State Physics (Freiburg, Germany) and AIM Infrarot-Module GmbH (Heilbronn, Germany). Besides imagers for the 8–12 micron long-wavelength infrared (LWIR) and 3–5 micron mid-wavelength infrared (MWIR) regimes, a LWIR/MWIR dual-band QWIP FPA will also be discussed.
报告人简介：Harald Schneider received the diplomas in physics and in mathematics from the University of Tübingen, Germany, in 1985 and completed his PhD thesis at the Max-Planck Institute for Solid State Research, Stuttgart, Germany, in 1988. In 1989, he joined the Fraunhofer Institute for Applied Solid State Physics, Freiburg, Germany. Since 2005 he is a department head at the Forschungszentrum Dresden Rossendorf, Dresden, Germany. His research interests include optoelectronic properties of semiconductors, ultrafast spectroscopy, high-speed optoelectronics, and detectors for the infrared and THz regimes. For the development of infrared cameras of highest thermal resolution, he and his colleagues were awarded the 2001 German Science Foundation Award. He co-authored about 180 publications and holds 4 patents.
