摘要

将原子力显微镜调谐叉型悬臂与光泵浦探针光的延迟时间调制方法相结合，开发了一种时间分辨力显微镜技术。在探针光的照射过程中，偶极子的瞬时形成引起探针和样品之间的力，从而能够稳定地获取具有高信噪比的时间分辨力信号。我们成功地测量了块体WSe2中光激发载流子的表面重组和扩散动力学，这在时间分辨扫描隧道显微镜中由于隧道电流的影响而具有挑战性。

Time-resolved force microscopy using delay-time modulation method

Abstract We developed a time-resolved force microscopy technique by integrating the Atomic Force Microscope tuning fork-type cantilever with the delay time modulation method of optical pump-probe light. During the irradiation of the probe light, the instantaneous formation of dipoles induces a force between the probe and the sample, enabling the stable acquisition of a time-resolved force signal with a high signal-to-noise (SN) ratio. We successfully measured the dynamics of surface recombination and diffusion of photoexcited carriers in a bulk WSe2, which are challenging due to the effect of tunneling current in the time-resolved Scanning Tunneling Microscopy.
