0107376HillhouseThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a six month postdoctoral research fellowship by Dr. Hugh W. Hillhouse to work with Dr. Teun M. Klapwijk at Delft University of Technology in the Netherlands.This project will study organic based materials that can be used in the development of semiconductors and superconductors. Recently there was an important breakthrough in the synthesis of organic molecular crystals. This resulted in high quality crystals that are insulating, but may be converted to a semiconductor, metallic, or superconducting state by simply turning a knob. This unique property provides experimenters with an extra degree of freedom to study the fundamental physics of the solid state. However, still little is known about the synthesis of these crystals. The objective of this project is to first study the growth of these crystals with particular emphasis on correlating structural order, defects, and purity to the measured electronic structure. The crystals will then be used as model systems to study the fundamentals of charge transport, the nature of the metal-insulator transition, and the origin of superconductivity.Dr. Klapwijk is an expert on superconductivity, nanoscopic phenomena, and charge transport in organic materials. He also has strong collaborative ties to Philips Research Laboratories where there is an active program to develop electronic devices based on organic transistors.

0107376Hillhouse国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该项目的奖项为联合研究以及使用国外独特或互补的设施、专业知识和实验条件提供了机会。该奖项将支持 Hugh W. Hillhouse 博士与荷兰代尔夫特理工大学的 Teun M. Klapwijk 博士合作为期六个月的博士后研究奖学金。该项目将研究可用于开发半导体和超导体的有机基材料。 近期有机分子晶体的合成取得重要突破。 这样就产生了绝缘的高质量晶体，但只需转动旋钮即可将其转换为半导体、金属或超导状态。 这种独特的性质为实验者提供了额外的自由度来研究固态的基础物理。 然而，人们对这些晶体的合成知之甚少。 该项目的目标是首先研究这些晶体的生长，特别强调将结构顺序、缺陷和纯度与测量的电子结构相关联。 然后，这些晶体将被用作模型系统来研究电荷传输的基本原理、金属-绝缘体转变的性质以及超导性的起源。 Klapwijk 是超导性、纳米现象和有机材料电荷传输方面的专家。他还与飞利浦研究实验室有着密切的合作关系，该实验室有一个积极的计划来开发基于有机晶体管的电子设备。
