U.S.-Korea Cooperative Research on Dynamic Processes on Femto-Second Time Scales

9414072责任本奖项提供资金，以允许佛罗里达大学物理系James W.Dufty博士和Christopher J.Stanton博士与韩国首南大学物理系Chang Sub Kim博士进行为期36个月的以毫秒为时间尺度的动态过程合作研究计划。这项研究的目的是为广泛的光谱研究提供一个安全的理论框架，将现有的理论推广到较短的时间，并提供与实验进行比较的实用模型。令人感兴趣的原型系统包括具有实际重要性的化合物半导体，如GaAs和InP。要研究的现象的例子是飞秒泵浦-探测实验中观察到的短时间内的电荷载流子动力学。拟议的实验和理论方法的结合将用于提供有关半导体中激发载流子的物理以及它们如何影响电子和光电子器件性能的基本信息。合作者在与他们提议的项目领域相关的研究方面获得了相当多的补充经验。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学与工程基金会(KOSEF)的支持。***

9414072 Dufty This award provides funds to permit Drs. James W. Dufty and Christopher J. Stanton, Department of Physics, University of Florida, to pursue with Dr. Chang Sub Kim, Department of Physics, Chonnam University, Korea, for 36 months, a program of cooperative research on dynamic processes on femto-second time scales. The objective of this research is to provide a secure theoretical framework for a wide class of spectroscopic studies, a generalization of existing theory to short times, and practical models for comparisons with experiments. Prototype systems of interest include compound semiconductors of practical importance such as GaAs an InP. Examples of phenomena to be studied are charge carrier dynamics at short times as observed by femptosecond pump-probe experiments. The proposed combination of experimental and theoretical approaches will be used to provide fundamental information about the physics of excited carriers in semiconductors and how they impact electronic and optoelectronic device performance. The collaborators have acquired considerable complementary experience in research related to the field of their proposed project. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF). ***
