Jay Switzer, Department of Chemistry, University of Missouri-Rolla, is jointly supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program and the Solid State Chemistry Program for studies of nanostructured metal oxide semiconductors. Using various electrodeposition techniques, Switzer will prepare magnetic metal oxide superlattices, size-and shape-focused metal oxide nanostructures and epitaxial metal oxide layers on single-crystal silicon, gold, copper and indium phosphide. The metal oxides of interest include copper oxide, zinc oxide and iron oxide. Electrodeposition allows control of the applied potential, current and solution pH during electrodeposition, leading to control of the composition as well as the size and shape of the growing crystalline nanostructure. These nanostructured crystalline metal oxides have widespread potential applications in electronics, specifically giant magnetoresistance, spintronics and anisotropic electronic components. This interdisciplinary research area will also provide training for students and research associates in the important area of nanoscience.

密苏里大学罗拉分校化学系的 Jay Switzer 得到了无机、生物无机和有机金属化学项目和固态化学项目的联合支持，用于纳米结构金属氧化物半导体的研究。 Switzer将利用各种电沉积技术在单晶硅、金、铜和磷化铟上制备磁性金属氧化物超晶格、尺寸和形状集中的金属氧化物纳米结构以及外延金属氧化物层。感兴趣的金属氧化物包括氧化铜、氧化锌和氧化铁。电沉积可以控制电沉积过程中施加的电位、电流和溶液 pH 值，从而控制生长的晶体纳米结构的成分以及尺寸和形状。这些纳米结构晶体金属氧化物在电子领域具有广泛的潜在应用，特别是巨磁阻、自旋电子学和各向异性电子元件。这个跨学科研究领域还将为纳米科学重要领域的学生和研究助理提供培训。
