9302173 Gladfelter At the core of all materials research is the need to know composition and structure. These determine the physical properties and may reflect the synthesis and processing history of the materials. Rutherford backscattering (RBS) and forward recoil spectrometry (FRES) are two powerful tools for establishing the compositions and depth profiles of thin films. Several programs at the University of Minnesota will make use of this RBS System, including a) using RBS to evaluate diffusion processes in olivine that may contribute to movement of material in the earth's mantle, b) using RBS to characterize compositions of high temperature superconducting metal oxide films c) using RBS to characterize chemical reactions that occur at interfaces and control the fracture mechanics of the films, d) using FRES to quantify the hydrogen (or deuterium) content of films grown from organometallic precursors, e) using FRES to study diffusion of polymers. ***

9302173格拉菲尔特在所有材料研究的核心是需要知道组成和结构。这些参数决定了材料的物理性能，并可反映材料的合成和加工历史。卢瑟福背散射(RBS)和前向反冲光谱(FRES)是建立薄膜成分和深度分布的两种强有力的工具。明尼苏达大学的几个项目将利用这个RBS系统，包括a)使用RBS来评估可能有助于地球地幔中物质运动的橄榄石中的扩散过程，b)使用RBS来表征高温超导金属氧化物薄膜的成分，c)使用RBS来表征发生在界面上的化学反应并控制薄膜的断裂机制，d)使用FRES来量化由有机金属前体生长的薄膜的氢(或氢)含量，e)使用FRES来研究聚合物的扩散。***
