Structure and Reactivity of Amorphous Solids

实验物理化学专业授予Charles wright教授“非晶态固体的结构和反应性”奖。本研究涉及形成非晶和结晶固体薄膜的新技术，开发表征这种薄膜中分子无序的性质和程度的方法，并评估这种无序对化学反应性的影响。主要的科学目标是证明无序材料的物理性质如何与更熟悉的液体和结晶固体的性质相关联，并确定无序（局部浓度和分子取向的波动）对固体材料的化学反应活性的影响，特别是对链式反应的影响。这些基本知识将为理解固态化学在许多商业和技术应用中的重要基础，如非晶半导体、光存储器、金属薄膜光刻剂和高能材料的稳定。

The Experimental Physical Chemistry Program has made an award to Professor Charles Wight to support his work on "Structure and Reactivity of Amorphous Solids". This investigation concerns new techniques for forming amorphous and crystalline solid films, for developing methods for characterizing the nature and extent of molecular disorder in such films and to assess the effects of this disorder on chemical reactivity. The principal scientific objectives are to demonstrate how the physical properties of disordered material relate to more familiar properties of liquids and crystalline solids and to determine the effects of disorder (fluctuations in local concentrations and molecular orientations) on the chemical reactivity of solid materials, especially with respect to chain reactions. This basic knowledge will provide an important foundation for understanding solid-state chemistry in a number of commercial and technological applications such as amorphous semiconductors, optical memories, metal films photoresists, and stabilization of high energy materials.
