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上碱金属覆盖层的结构、动力学和相变。本研究采用的主要技术是he-原子散射（HAS），实验将在R. B. Doak教授的实验室用最先进的仪器进行。这些实验的主要目的是研究he原子与碱金属表面的相互作用，研究碱金属与金属表面键的动力学与碱金属覆盖的函数关系，以及研究厚碱金属薄膜的晶格动力学。目标是增加对简单金属吸附剂，简单金属表面以及He原子如何与它们耦合的理解。此外，本研究亦会利用低能电子显微镜（LEEM），在曾教授的实验室进行石墨相互作用的探索性实验。这些实验将为研究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：教授研究生水平的表面物理课程；发起并组织了一个备受瞩目的研讨会项目，邀请美国各地的女科学家和女工程师在亚利桑那州立大学发表演讲；并计划举办一系列女性物理学研讨会，旨在提高女性物理学家的知名度，特别是那些处于职业生涯早期的女性，她们将从曝光中受益最多。为了讨论研究兴趣和气候、家庭和就业前景等问题，将发起物理学和相关学科的女性午餐会议。

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.
