小行星9705343 这个跨学科的研究项目将研究配体稳定的纳米簇阵列的化学合成和电输运性质。 将研究一维和二维系统，后者的结构主要用于开发必要的化学，以实现制造高度有序和电寻址的一维金属纳米簇阵列的主要目标。 多分散性，结构紊乱和捕获电荷的影响将被调查，并将分子水平的接触，如门电极，直接使用分支，螺旋多肽分子支架结构的长期目标将被寻址。 该项目涉及一个很好的综合教育和研究工作，旨在使用生物分子组织金属纳米团簇，并包括作为一个目标，创造一个室温库仑阻塞设备作为CMOS存储设备的可能替代品。 它涉及一组2名研究生，一名合成化学家和一名物理学家作为PI，他们似乎合作得很好，并在各自的专业领域有着出色的业绩记录。该项目将为学生提供跨学科的研究经验和培训，在合成化学和凝聚态物理领域，如运输测量。 这些学生还将在霍华德休斯医学研究所的分子生物学研究所工作， 簇阵列，使用AFM和STM。 ***

9705343 Wybourne This interdisciplinary research project will investigate the chemical synthesis and electrical transport properties of ligand stabilized nanocluster arrays. Both one- and two-dimensional systems will be investigated, with the latter structures used primarily to develop the necessary chemistry for the principal goal of fabricating highly ordered and electrically addressable one-dimensional arrays of metal nanoclusters. The effects of polydispersity, structural disorder and trapped charge will be investigated, and the long term goal of incorporating molecular level contacts, such as gate electrodes, directly to molecular scaffold structures using branched, helical polypeptides will be addresed. %%% This project involves a well integrated education and research effort aimed at using biomolecules to organize metal nanoclusters and includes as a goal the creation of a room temperature Coulomb blockade device as a possible replacement for CMOS memory devices. It involves a group of 2 graduate students, and a synthetic chemist and a physicist as PIs, both of whom appear to work well together and have excellent established outstanding track records in their various fields of expertise. The project will provide students with interdisciplinary research experience and training in synthetic chemistry and in condensed matter physics areas such as transport measurements. The students will also be working within the Institute of Molecular Biology at the Howard Hughes Medical Institute to characterize the cluster arrays using AFM and STM. ***
