中文摘要
布朗大学工程系将根据NSF工程研究设备补助金购买飞秒激光设备,该补助金将专门用于支持工程研究。激光设备将用于支持几个研究项目,包括半导体纳米结构的时间分辨光谱学。这项工作包括正在开发用于短可见波长光电子应用的宽带隙半导体材料,以及具有高迁移率的二维和低维电子的异质结构。这种激光仪器使超快光学技术成为可能,将能够实时跟踪几纳米尺度的小型半导体结构中的电子激发。
英文摘要
The Division of Engineering at Brown University will purchase femtosecond laser equipment under this NSF Engineering Research Equipment Grant which will be dedicated to support research in engineering. The laser equipment will be used to support several research projects, including in particular time-resolved optical spectroscopy of semiconductor nanostructures. The work includes wide-bandgap semiconductor materials which are being developed for optoelectronic applications at short visible wavelengths as well as heterostructures in which two- dimensional and lower dimensional electrons are of high mobility. The ultrafast optical techniques made possible by this laser instrumentation will enable the tracking of electronic excitations in small semiconductor structures on a scale of a few nm in real time.
