At the present time, their size has arrived at nanometer scale, and it approximately takes several picoseconds, or even shorter time, for free carriers to transport during such small distances. Therefore, research of carrier dynamics in silicon on shorter and shorter time scale is urgently developed. Processes on such short time scale are difficultly measured by traditional electronic method, so ultrafast spectroscopy method is the only choice of carrying out such experiments. Additionally, application of photoelectric detectors is severely influenced by laser.
