Description

The comprehensive knowledge of the mechanism involved in the charge carrier separation in nanoscale structures is of high interest regarding applications and fundamental researches. A microscopy technique that enables the visualization of subpicosecond carrier dynamics in nanometer-scale structures is laser-combined scanning tunneling microscopy [1]. OptoPulSTM simultaneously realizes STM spatial resolution together with the temporal resolution of the optical pump–probe technique.
