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). ***

小行星9414072 该奖项提供资金，允许博士詹姆斯W。Dufty和佛罗里达大学物理系的Christopher J. Stanton将与韩国全南大学物理系的Chang Sub Kim博士一起进行为期36个月的飞秒时间尺度上动态过程的合作研究计划。 本研究的目的是提供一个安全的理论框架，广泛的光谱研究，现有的理论推广到短时间内，与实验比较的实用模型。 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在短时间内观察到的飞秒泵浦探测实验的电荷载流子动力学。 实验和理论方法的结合将用于提供有关半导体中受激载流子的物理学以及它们如何影响电子和光电器件性能的基本信息。 合作者在与其拟议项目领域相关的研究方面获得了相当多的补充经验。 该项目与美国的目标有关-韩国合作科学计划，旨在通过科学信息，思想，技能和技术的交流以及通过互利问题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。 韩国对该项目的参与得到了韩国科学和工程基金会的支持。 ***
