项目摘要

Technical Narrative: This U.S.-Egypt collaborative research project involving the University of North Carolina (UNC) and Cairo University is in the general area of Si-SiGe heterostructures. Project funding will enable the team from Cairo University to work for various periods of time in the laboratory of Dr. Sean Washburn at UNC as well as the IBM Watson Research Center. Additionally, Dr. Washburn will spend one week visiting the laboratory of Dr. Khalid Ismail of Cairo University. The investigators will perform a series of transport experiments on small point contacts, lateral resonant tunneling devices, and interferometers. The proposed experiments will (1) extend the study of ballistic transport to new materials systems, (2) provide a broader base of experimental data to test theoretical predictions on ballistic transport, (3) provide the first system for experimental data for testing recent predictions of conductance quantization in one-dimensional Luttinger liquid, and (4) allow testing of new predictions for electrostatic interference effects. This project in materials research fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Egypt to combine complementary talents and pool research resources in areas of strong mutual interest and competence.

技术叙述：这个涉及北卡罗来纳大学 (UNC) 和开罗大学的美国-埃及合作研究项目属于 Si-SiGe 异质结构的一般领域。项目资金将使开罗大学的团队能够在北卡罗来纳大学 Sean Washburn 博士的实验室以及 IBM 沃森研究中心工作不同时期。此外，Washburn博士还将用一周时间参观开罗大学Khalid Ismail博士的实验室。研究人员将在小点接触、横向谐振隧道装置和干涉仪上进行一系列传输实验。拟议的实验将（1）将弹道输运研究扩展到新材料系统，（2）提供更广泛的实验数据基础来测试弹道输运的理论预测，（3）提供第一个实验数据系统，用于测试一维卢廷格液体中电导量子化的最新预测，以及（4）允许测试静电干扰效应的新预测。该材料研究项目通过使美国和埃及的领先专家能够在共同感兴趣和能力强的领域结合互补人才并汇集研究资源，实现了推进科学知识的计划目标。
