Development of an Ultrahigh Vacuum Nanocircuit Characterization System for Research and Student Training

这笔赠款提供了一个超高真空（UHV）表面科学室在欧文市的加州大学的发展，为纳米尺度材料的研究，特别是纳米电子器件的电子性能和潜在的电子应用的支持。 UHV系统将有助于建立理解纳米级电子器件及其化学环境之间相互作用的基础。特高压室将配备用于电输运测量的专用样品处理装置。 表面科学技术将应用于高表面积的纳米材料，如碳纳米管，以帮助确定其真正的传输特性，并研究其与分子吸附物的相互作用。 该系统将提供精心控制的化学状态和有限的吸附物种，以允许化学或生物传感器应用的电子纳米材料的调查。该装置将影响在加州大学欧文分校就读于化学和材料物理（ChaMP）计划的20多名学生的研究生教育。 该研究生课程强调物理，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积极的学习环境，以向新生介绍研究生水平的研究。 学生将通过研究化学环境对纳米管和纳米线或簇的电子性质的影响，通过制备有和没有吸附物的设备来获得经验。 学生将获得化学，物理和生物学科与纳米尺度系统交叉的新视角。

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.
