Analysis and control of the ultra fast phenomena in nano-scaleand its application to the development of new functional materials and devices.

利用我们在2005年购买的波长可调谐激光器，通过与使用传统的光泵浦探测技术观察到的载流子动力学的结果进行比较，分析了隧穿电流的时间依赖性。因此，我们已经证实，我们可以探测本地的光生载流子动力学使用我们的激光组合STM。随着一个新的想法的引入，我们已经成功地开发了新的系统，使我们能够观察从亚皮秒到微秒范围内的载波动态在1/100至1/10000的第一代系统的数据采集时间。

Using the wavelength-tunable laser which we bought in 2005, time-dependence of the tunneling current was analyzed by comparing the results with the carrier dynamics observed using the conventional optical pump-probe technique. Thereby, we have confirmed that we can probe the local photocarrier dynamics using our laser-combined STM. With the introduction of a new idea, we have succeeded in developing the new system which enables us to observe the carrier dynamics from sub-picosecond to microsecond range in 1/100 to 1/10000 data acquisition time of the first generation system.
