Electronic Structure of Large Semiconductor Clusters

这项来自实验物理化学计划的设备赠款正在帮助Alivisatos教授获得他研究包含数千个原子的半导体团簇的合成和性质所需的关键设备。资金正用于购买液氦低温恒温器和低温恒温控制器，用于对尺寸几乎一致的半导体团簇的最低激发态和较高激发态进行光电研究。还将购买用于本实验诊断工作的示波器和其他设施。

This equipment grant from the Experimental Physical Chemistry Program is helping Professor Alivisatos to obtain critical equipment needed in his investigations of the synthesis and properties of semiconductor clusters containing several thousand atoms. Funds are being used to purchase a liquid helium cryostat and a cryostatic temperature controller for use in electro-optical studies of the lowest excited state and higher excited states of semiconductor clusters of nearly uniform size. An oscilloscope for diagnostic work in this experiment and other facilities will also be purchased.
