Abstract
In this paper, we report experimental results of picosecond electrical transients pumped by ultrashort laser pulses on a coplanar strip line with an ultrafast scanning tunneling microscope. The resolved transient signal has a rise time in non-contact mode of 1.21 ps and the FWHM is 1.19 ps. Our measurements showed that the amplitude and the shape of the transient signals are independent of the magnitude and the polarity of the dc tunneling current, which confirms the capacitive coupling of the transient signal between the tip and the coplanar transmission line.
