U.S.-Argentina Cooperative Research: Charge and Energy Relaxation at Insulators and at Surfaces

这个美洲项目奖将资助弗吉尼亚大学的Raul Baragiola博士和阿根廷Quimica工业技术研究所（INTEC）的Edith Goldberg博士之间的合作研究项目。他们将研究由紫外线光子、离子或电子的高能激发而产生的绝缘薄膜和金属表面的基本过程。要解决的主要问题是，静电电荷是如何在辐照下产生的，以及由此产生的电场如何影响电子能量的弛豫，使其变成光、损伤和原子粒子的发射。绝缘体和金属电极之间的界面如何中和空穴和松弛能量的问题也将被研究。这些是许多学科的核心基本问题，包括绝缘体的工业应用（电气、电子和静电复印工业）、大气物理学（电荷）和生物学（对细胞的辐射损害）。两个研究小组的互补性专门知识将允许对该项目采取一系列实验和理论方法，这将证明对两国都有利。* * *

9724820 Baragiola This Americas Program award will fund a collaborative research project between Dr. Raul Baragiola, University of Virginia, and Dr. Edith Goldberg, Instituto de Desarrollo Tecnologico para la Industria Quimica (INTEC), Argentina. They will investigate fundamental processes in insulating thin films and at metal surfaces resulting from high energy excitations by UV photons, ions or electrons. The main questions to be addressed are how electrostatic charges are developed under irradiation, and how the resulting electric fields affect the relaxation of the electronic energy into light, damage, and the emission of atomic particles. The problem of how the interface between the insulator and a metal electrode neutralizes holes and relaxes energy will also be studied. These are fundamental problems central to a number of disciplines, including industrial applications of insulators (electrical, electronic and xerography industries), atmospheric physics (electrical charging), and in biology (radiation damage to cells). The complementary expertise of both research groups will allow a range of experimental and theoretical approaches to the project that will prove beneficial to both countries. ***
