VPW: He-Atom Scattering Studies of Alkali Metal Overlayers (Materials Research)

Renee Diehl博士的研究涉及金属和石墨表面碱金属覆盖层的结构，动力学和相变的研究。 本研究所采用的主要技术是氦原子散射技术（HAS），实验将在R。B。在最先进的仪器上做实验。 这些实验的主要目的是研究氦原子与碱金属表面的相互作用，研究碱金属键与金属表面的动力学作为碱金属覆盖率的函数，并研究厚碱金属膜的晶格动力学。 目标是增加对简单金属吸附物、简单金属表面以及He原子如何与它们耦合的理解。 在I教授的实验室，还将使用低能电子显微镜（LEEM）对石墨相互作用进行探索性实验。阿聪 这些实验将为碱金属嵌入石墨的微观过程和动力学提供新的信息。 将开展的互动活动包括：教授表面物理学研究生课程;发起和组织一个引人注目的研讨会方案，将使来自美国各地的女科学家和工程师在亚利桑那州立大学发言;并计划举办一系列旨在提高女物理学家知名度的女物理学家座谈会，尤其是那些处于职业生涯早期的人，他们将从曝光中受益最多。 将发起物理学和相关学科的妇女午餐会议，以讨论研究兴趣和气候、家庭和就业前景等问题。

Dr. Renee Diehl's research involves the study of structures, dynamics and phase transitions in overlayers of alkali metals on metal and graphite surfaces. The main technique to be employed in this study is He-atom scattering (HAS), and experiments will be carried out in the laboratory of Professor R. B. Doak on a state- of-the-art apparatus. The main purposes of these experiments are to study the He-atom interaction with alkali surfaces, to study the dynamics of the alkali metal bond to metal surfaces as a function of alkali metal coverage, and to study the lattice dynamics of thick alkali metal films. The goal is to increase the understanding of simple metal adsorbates, simple metal surfaces and how He atoms couple to them. Exploratory experiments will also be carried out using low-energy electron microscopy (LEEM) on graphite interacalation in the laboratory of Professor I. Tsong. These experiments should provide new information on the microscopic process and kinetics of alkali metal intercalation into graphite. Interactive activities to be carried out include: teaching a graduate level course in surface physics; initiating and organzing a high-profile seminar program which will bring women scientists and engineers from all over the US to speak at Arizona State University; and planning a women in physics colloquim series aimed at increasing the visibility of women physicists, particularly ones who are in their early careers and who will benefit most from the exposure. Lunchtime meetings of women in physics and related disciplines will be initiated in order to discuss research interests and issues such as climate, families, and employment prospects.
