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

利哈伊大学化学系的格雷戈里·S·弗格森教授和迪米特里·维泽诺夫将获得专业研究与仪器(MRI)项目的这一奖项，他们将获得一台光谱椭偏仪。它将用于各种研究项目，包括：1)单分子膜的电化学自组装，2)基于单分子阵列的生物传感器的开发，3)硫系玻璃大块和薄膜光学性质的光诱导变化，3)用于能源的高In含量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-生物分子复合膜的开发，7)胶合型朗缪尔-布洛格特双层膜，8)玻璃科学，碲酸盐纤维的加工和光学性能，9)半导体中的氢。椭偏仪是一种非常简单的表面表征技术，因为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。它经常是对薄膜、软或生物界面和材料进行常规表征的首选技术。这项收购将大大有助于对研究生和本科生研究人员以及博士后研究员进行跨学科研究的最先进的培训。它将为纳入本科生课程提供强有力的资源。

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.
