MRI: Acquisition of a Spectroscopic Ellipsometer for Surface and Materials Analysis at Lehigh University

通过这项来自主要研究和仪器（MRI）项目的奖励，理哈伊大学化学系的Gregory S. Ferguson教授和Dimitri Vezenov教授将获得一个光谱椭偏仪。它将用于各种研究项目，包括研究：1)电化学定向自组装单层膜，2)基于单分子阵列的生物传感器的发展，3)光诱导硫系玻璃体和薄膜光学性质的变化，3)用于能源应用的高铟InGaN和AlInGaN半导体，4)溶胶-凝胶涂层厚度的测定，5)分子设计表面，6)纳米多孔无机、聚合物和聚合物-生物分子复合膜的发展，7) Langmuir-Blodgett双分子层，8)玻璃科学，碲酸盐纤维的加工和光学特性，9)半导体中的氢。椭圆偏振法是一种非常简单的表面表征技术，它可以提供定量测量-在最简单的情况下，它是薄膜或界面的厚度。它通常是常规表征薄膜、软界面或生物界面和材料的首选技术。此次收购将为跨学科研究的研究生和本科生研究人员以及博士后研究人员提供最先进的培训。它将为纳入本科课程提供一个强大的资源。

With this award from the Major Research and Instrumentation (MRI) program, Professor Gregory S. Ferguson and Dimitri Vezenov of the Department of Chemistry at Lehigh University will acquire a spectroscopic ellipsometer. It will be used in a variety of research projects including studies of: 1) the electrochemically directed self-assembly of monolayer films, 2) development of biosensors based on single molecule arrays, 3) photoinduced changes in the optical properties of chalcogenide glass bulk and thin films, 3) high indium-content InGaN and AlInGaN semiconductors for energy applications, 4) determination of the thickness of sol-gel coatings, 5) molecularly designed surfaces, 6) the development of nanoporous inorganic, polymeric and polymer-biomolecule composite membranes, 7) glued Langmuir-Blodgett bilayers, 8) glass science, processing and optical properties of tellurite fibers, and 9) hydrogen in semiconductors.Ellipsometry is an exceptionally simple technique for surface characterization in terms of the quantitative measurement that it can provide - in the simplest case, it is the thickness of a film or interface. It is frequently a technique of first choice for routine characterization of thin films, soft or biological interfaces and materials. The acquisition will contribute significantly to state-of-the-art training of graduate and undergraduate researchers, as well as postdoctoral fellows, in interdisciplinary studies. It will provide a robust resource for incorporation into the undergraduate curricula.
