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.

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，专门用于支持工程研究。 该激光设备将用于支持多个研究项目，特别包括半导体纳米结构的时间分辨光谱。 这项工作包括为短可见波长的光电应用而开发的宽带隙半导体材料，以及二维和低维电子具有高迁移率的异质结构。 这种激光仪器实现的超快光学技术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。
