Solid State/Materials Preparation And Characterization Initiative

卡尔文学院的物理系打算加强其 中等和高等教育的教学能力 本科生，基本的实验技术，用于 固体物理学及材料的邻近领域 科学 为此，我们选择了 热、磁和电测量，并具有 设计了一个仪器倡议，使这些 材料性能要在广泛的范围内测量， 温度 该倡议还向学生介绍了一些 材料生产的基本技术广泛应用于 凝聚态物理学 我们的倡议获得了一个差示扫描量热仪 比热容和相变研究系统 转变;磁化率系统适用于 8-325 K范围;和一个非常通用的电子仪器 用于电传输和极化的包装 测量. 一个封闭的循环制冷机正在收购， 提供温度控制的磁和电 测量.最后，为了准备样品，我们 我已取得了一个简单的炉，基本真空蒸发 和溅射系统，用于块状和薄膜样品， 材料准备。

Calvin College's Physics Department intends to strengthen its capabilities in teaching, to intermediate- and upper-level undergraduates, the fundamental experimental techniques used in solid-state physics and the neighboring areas of materials science. To do so, we have selected the major areas of thermal, magnetic, and electrical measurements, and have devised an instrumentation initiative which enables these material properties to be measured over a wide range of temperature. The initiative also introduces students to some of the basic techniques of materials production widely used in condensed-matter physics. Our initiative acquired a differential scanning calorimeter system, for study of specific heat capacity and phase transitions; a magnetic susceptibility system applicable over the 8-325 K range; and a very versatile electronic instrument package for electrical transport and polarizability measurement. A closed-cycle cryocooler is being acquired to provide the temperature control for the magnetic and electrical measurements. Finally, for purposes of sample preparation, we have acquired a simple furnace, and basic vacuum evaporation and sputtering systems, for bulk and thin-film sample and materials preparation.
