CAREER: Soft and Hard Chemical Routes to Nanoscale Metal Chalcogenide Materials

化学系的分析和表面化学项目将这一职业奖项授予西北大学，以研究纳米级过渡金属二卤化物材料的合成和性能。获得该奖项后，特里·奥多姆教授将探索合成富勒烯类无机MX2(M=Nb，Ta；X=S，Se)材料的途径，以及通过控制尺寸、结构和插层化学来改变电子性质的策略。主要感兴趣的是系统的表面和整体结构以及有限大小如何影响集体现象的性质，如电荷密度波和超导电性。变温扫描隧道显微镜(STM)和导电原子力显微镜(AFM)将用于电子表征。奥多姆教授还将把纳米技术融入课堂活动，并使高中科学教师能够参与研究项目。她正在开发纳米科学的课程，其中包括接触尖端仪器和让本科生及早接触研究。特里·奥多姆教授将开发基于过渡金属二卤化物化合物的富勒烯类纳米材料的制备方法，并通过使用原子和高光谱分辨率技术研究其电子性质。这些研究的结果提供了关于材料性质的基本信息，这些材料性质控制着表面态的超导和电子电荷陷阱。教育部分将扩大对研究和纳米科学的认识，并为高中科学教师提供新的学习机会。

The Analytical and Surface Chemistry Program in the Division of Chemistry makes this Career award to Northwestern University to investigate the synthesis and properties of nanoscale transition metal dichalcogenide materials. With this award, Professor Teri Odom will explore routes to inorganic, fullerene-like MX2 (M = Nb, Ta; X = S, Se) materials and strategies for varying the electronic properties through control of size, structure and intercalation chemistry. Of primary interest is how the surface and bulk structure and finite size of a system can influence the properties of collective phenomena, such as charge density waves and superconductivity. Variable temperature scanning tunneling microscopy (STM) and conducting atomic force microscopy (AFM) will be used for electronic characterization. Professor Odom will also integrate nanoscale technology into classroom activities and enable participation of high school science teachers in research projects. She is developing curriculum in nanoscience that includes access to cutting-edge instrumentation and early exposure of undergraduate students to research. Professor Teri Odom will develop methods for the preparation of fullerene-like, nanoscale materials based on transition metal dichalcogenide compounds and investigate the electronic properties through the use of atomic and high spectroscopic resolution techniques. The results of these studies provide fundamental information about materials properties that control superconductivity and electronic charge trapping by surface states. The education component will broaden awareness of research and nanoscale science and open new learning opportunities for high school science teachers.
