Presidential Young Investigator Award

德宾博士被选为总统青年研究员。他积极从事分子束外延生长的x射线超晶格的基础研究。在国家科学基金的研究项目中，他将继续研究包括x射线和电子动力学衍射现象在晶体表面研究中的应用。整个程序是基于从晶体波场激发的散射x射线和电子产量中获得结构信息，在动态衍射理论的背景下。通过了解真空中裸露的晶体表面，然后通过在该表面缓慢添加不同的原子种类获得结构，可以推导出外延生长的机制。这些知识对于制造具有原子尺度工程特性的新材料是必不可少的。

Dr. Durbin has been selected as a Presidential Young Investigator. He is active in fundamental research on x-ray superlattices grown by molecular beam epitaxy. In the research program for the National Science Foundation he will pursue studies to include the application of x-ray and electron dynamical diffraction phenomena to the investigation of crystal surfaces. The entire program is based on deriving structural information from the scattered x-ray and electron yields from crystal-wave field excitations, within the context of dynamical diffraction theory. By obtaining an understanding of bare crystal surfaces in vacuum, and then the structures obtained by slowly adding a different atomic species to that surface, the mechanics of epitaxial growth can be derived. This knowledge is essential for fabrication of new materials with properties engineered on an atomic scale.
