9802892 smalley该奖项为Rice大学的研究人员购买最先进的超高真空、变温扫描隧道/原子力显微镜仪器提供了部分支持。该仪器将满足物理系、化学系、电子工程系和计算机工程系的一群教职员工对纳米级成像、局部光谱学、单分子器件制造和传输测量能力的需求。该仪器的主要焦点是在一系列科学和技术背景下研究富勒烯纳米管。该系统将允许以下研究活动：1)富勒烯纳米管和其他感兴趣的纳米颗粒的成像和光谱，2)基于单分子和纳米颗粒的器件结构的组装，3)混合电子束光刻/分子自组装器件制造方法的表征，4)富勒烯STM尖端的制造、表征和成像应用。5)利用C60吸附的STM尖端对功能化富勒烯纳米管和纳米管缺陷进行结构成像和光谱研究；6)纳米聚合物的相变和结构转变的温度依赖纳米尺度成像和分析。该仪器将是莱斯大学唯一的超高真空或变温STM/AFM仪器。因此，它将提供重要的新实验能力，增强几个研究小组正在进行的项目，并为有不断增长的研究项目的初级教师提供最先进的纳米设备。% % % * * *

9802892SmalleyThis award provides partial support for the acquisition of equipment to provide Rice University researchers with a state-of-the-art ultrahigh vacuum, variable-temperature scanning tunneling/atomic force microscope instrument. This instrument will address the needs for nanoscale imaging, localized spectroscopy, and single molecule device fabrication and transport measurement capabilities for a cluster of faculty members in the Physics, Chemistry, and Electrical and Computer Engineering Departments. A primary focus for this instrument is the study of fullerene nanotubes in a range of scientific and technological contexts. The system will allow the following research activities:1) imaging and spectroscopy of fullerene nanotubes and other nanoparticles of interest, 2) assembly of single-molecule and nanoparticle-based device structures, 3) characterization of hybrid e-beam lithography/molecular self-assembly device fabrication methods, 4) fabrication, characterization, and imaging applications of fullerene STM tips: C60- adsorbed STM tips, and fullerene nanotube AFM/STM tips,5) structural imaging and spectroscopic investigations of functionalized fullerene nanotubes and nanotube defects using C60-adsorbed STM tips,6) temperature-dependent nanoscale imaging and analysis of the phase transitions and structural transformations in nanosized polymers. This instrument will be the only ultrahigh vacuum or variable temperature STM/AFM instrument at Rice University. It will therefore provide significant new experimental capabilities, enhancing the ongoing programs of several research groups as well as providing a state-of-the-art nanoscale facility for junior faculty with growing research programs. %%%***
