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. ***

9705343怀伯恩这个跨学科研究项目将研究配体稳定的纳米团簇阵列的化学合成和电传输特性。一维和二维系统都将被研究，后一种结构主要用于开发必要的化学，以实现制造高度有序和可电寻址的金属纳米团簇一维阵列的主要目标。将研究多分散性、结构无序和陷阱电荷的影响，并解决将分子水平的接触，如门电极，直接结合到使用支化的螺旋多肽的分子支架结构的长期目标。该项目涉及一项旨在使用生物分子组织金属纳米团簇的良好整合的教育和研究工作，目标之一是创造一种室温库仑阻挡器件，作为可能的cmos存储器件的替代品。它涉及一个由两名研究生组成的小组，以及一名合成化学家和一名物理学家作为绩效指标，这两人似乎合作得很好，在各自的专业领域都有出色的业绩记录。该项目将为学生提供合成化学和凝聚态物理领域(如运输测量)的跨学科研究经验和培训。这些学生还将在霍华德·休斯医学院的分子生物学研究所工作，使用AFM和STM来表征集群阵列。***
