技术说明：“半导体微结构的超快工艺和光电特性”研究项目将由印度孟买塔塔基础研究所的阿罗拉博士和AT&Amp；这项提议的具体目的是：(1)促进TIFR科学家与沙阿博士及其团队在AT&AMP；贝尔实验室建立材料和器件结构制备系统和时间分辨测量实验室，用于研究新型半导体异质结和超晶格系统中的超快现象；以及(2)合作开展与上述材料的光电性质相关的研究计划。范围：这项建议是为支付首席调查员和参与这项合作的其他美国科学家的旅费和每日费用。从基础科学的角度来看，这一研究具有重要的意义，因为这些研究将对上述结构中的非平衡载流子动力学和新的光电现象提供基本的理解。此外，这项研究对于理解由非常特殊的薄膜异质结构制成的新型器件的运行具有很大的实际意义。这项提议符合美印合作科学计划的目标。***

Technical Narrative: The research project "Ultrafast Processes and Optoelectronic Properties of Semiconductor Microstructures" will be a collaboration between Dr. Arora of the Tata Institute of Fundamental Research, Bombay, India and Dr. Jagdeep Shah at the AT&T Bell Laboratories, Holmdel, N.J. The specific aims of this proposal are: (1) to facilitate cooperation between TIFR scientists and Dr. Shah and his group at the AT&T Bell Laboratories in setting up material and device structure preparation systems and time resolved measurement laboratory required for the study of the ultrafast phenomena in novel semiconductor heterostructure and superlattice systems, and (2) to collaborate in the research programs related to the optoelectronic properties of the above materials. Scope: This proposal is for funds to cover the travel and the per diem expenses of the Principal Investigator and other U.S. scientists participating in this collaboration. The investigation is of great importance form the basic science point of view as the studies will provide fundamental understanding of nonequilibrium carrier dynamics and new optoelectronic phenomena in the above structures. Furthermore, the study is of great practical relevance in understanding the operation of novel devices which have been made from very special thin film heterostructures. This proposal meets the objectives of the U.S. -India Cooperative Science Program. ***
