This grant provides support for the development of an ultra-high vacuum (UHV) surface science chamber at the University of California, Irvine, for the study of nanometer scale materials, specifically the electronic properties and potential electronic applications of nanoelectronic devices. The UHV system will help build a foundation of understanding for the interactions between nanoscale electronic devices and their chemical environment. The UHV chamber will be equipped with specialized sample handling for electrical transport measurements. Surface science techniques will be applied to high-surface area nanomaterials such as carbon nanotubes to help determine their true transport properties and to investigate their interactions with molecular adsorbates. The system will provide carefully controlled chemical states and limited adsorbed species to allow for investigations of electronic nanomaterials for chemical or biological sensor applications.This apparatus will impact the graduate education of more than 20 students enrolled at UC Irvine in the Chemical and Materials Physics (ChaMP) program. This graduate program stresses interdisciplinary connections between physics, chemistry and nanoscience, and it promotes an active learning environment with a hands-on laboratory rotation to introduce new students to graduate level research. Students will gain experience through investigations of the effects of chemical environment on the electronic properties of nanotubes and nanowires or clusters, by preparing devices with and without adsorbates. Students will gain new perspectives in the crossing of the disciplines of chemistry, physics and biology with the nanometer scale systems.

该赠款为加利福尼亚大学欧文分校的超高真空（UHV）表面科学室的开发提供了支持，以研究纳米尺度材料，特别是纳米电子设备的电子性质和潜在电子应用。 UHV系统将有助于为纳米级电子设备及其化学环境之间的相互作用建立理解的基础。 UHV腔室将配备用于电运输测量的专门样品处理。 表面科学技术将应用于高表面区域纳米材料（例如碳纳米管），以帮助确定其真正的运输特性，并研究其与分子吸附剂的相互作用。 该系统将提供精心控制的化学状态和有限的吸附物种，以允许研究化学或生物传感器应用的电子纳米材料。该设备将影响化学和材料物理学（CHAMP）计划的20多名学生的20多名学生的研究生教育。 该研究生计划强调物理，化学和纳米科学之间的跨学科联系，并通过动手实验室轮换促进了积极的学习环境，以将新生介绍给研究生水平的研究。 学生将通过研究化学环境对纳米管和纳米线或簇的电子特性的影响，通过准备和没有吸附剂的设备来获得经验。 学生将在化学，物理学和生物学学科与纳米量表系统的学科中获得新的观点。
