US-India Cooperative Research: Ultrafast Processes in Semiconductors, their Nanostructures and Optoelectronic Devices, Award in US and Indian Currencies

9702021 Shah描述：“半导体及其纳米结构和光电子器件的超快工艺”研究是一项新的合作，将孟买的塔塔基础研究所(TIFR)与新墨西哥大学、法国的CNRS实验室和新泽西州的贝尔实验室联系在一起。这项关于超快光电子学的研究是在印度第一个也是唯一一个皮秒光谱实验室的皮沙和皮阿罗拉的早期合作(INT-9022623)的基础上发展起来的。科学的焦点是：(1)低维半导体中的能量弛豫过程和速率，以及弛豫动力学对由这种结构制成的光电子器件性能的影响；(2)光电开关和电光采样器的制备和表征技术的发展；(3)利用这种光电器件测量超快电子器件的响应。范围：这项奖励将为美国和印度的合作者提供联系成本。这项研究虽然属于基础物理领域，但却是一个结合了超快光学和电子学的新兴研究领域。这一主题目前引起了相当大的兴趣，正在研究的设备可能在未来成为所有通信和计算机系统的组成部分。除了启动新的科学合作外，该项目还将有助于TIFR的超快光谱实验室成为世界级设施。所有的实验工作将在TIFR进行，将包括高级研究生和博士后。科技利益是互惠互利的，研究成果将发表在国际期刊上。***

9702021 Shah Description: The research "Ultrafast Processes in Semiconductors, their Nanostructures and Optoelectronic Devices, Award in US and Indian Currencies" is a new collaboration linking the Tata Institute of Fundamental Research (TIFR)in Bombay with the University of New Mexico, the CNRS Laboratoire de Microstructures et de Microelectronique in France, and Bell Laboratories, New Jersey. This research in ultrafast optoelectronics developed from an earlier collaboration (INT-9022623) between PI Shah and co-PI Arora of TIFR that established the first and only picosecond spectroscopy laboratory in India. The scientific focus is: (1) energy relaxation processes and rates in low-dimensional semiconductors and the effect of relaxation dynamics on the performance of optoelectronic devices fabricated from such structures; (2) development of fabrication and characterization techniques for photoconducting switches and electro-optic samplers, and (3) the use of such optoelectronic devices for measuring the response of ultrafast electronic devices. Scope: This award will provide the linkage costs for US and Indian collaborators. This study, while in the realm of fundamental physics, is in an emerging research area that combines ultrafast optics and electronics. The topic is of considerable current interest and the devices under study may in the future be integral to all communication and computer systems. In addition to initiating new scientific collaborations, this project will contribute toward the ultrafast spectroscopy laboratory at TIFR becoming a world-class facility. All the experimental work will be performed at TIFR and will include advanced graduate students and postdocs. The scientific and technological benefits are mutual and the research results will be published in international journals. ***
