In order to construct a measurement system, which enables the nanoscale probing of time resolved dynamics of the energy structures of material surfaces, we have developed a new measurement scheme of electric field modulation photo-absorption spectroscopy. The scheme is based on scanning tunneling microscopy using a supercontinuum light generated by ultra-short laser pulses as the wideband light source of Fourier transform interferometer. The performance of the scheme was demonstrated for the energy structure of semiconductor samples.On the other hand, the basic physical processes of measurement of carrier dynamics in semiconductor surfaces by STM and ultra-short laser pulses were analyzed by comparing model simulation data with experimental data. The optimum conditions for reliable measurement were determined.

为了构建一个测量系统，使纳米探测的时间分辨动力学的材料表面的能量结构，我们已经开发了一种新的测量方案的电场调制光吸收光谱。该方案基于扫描隧道显微镜，利用超短激光脉冲产生的超连续谱光作为傅里叶变换干涉仪的宽带光源。通过对半导体样品能量结构的分析，验证了该方案的有效性，并通过模型模拟数据与实验数据的对比，分析了STM和超短激光脉冲测量半导体表面载流子动力学的基本物理过程。确定了可靠测量的最佳条件。
