摘要

The mechanism underlying an ultrafast decay of a sample parameter appears that in a time-resolved tunnel current signal obtained by pulse-pair-excited scanning tunneling microscopy (PPX-STM) was theoretically and experimentally investigated. It was shown that the nonlinear dependence of the tunnel current on the sample parameter allows us to observe the decay process in a PPX-STM experiment even when the sample parameter itself does not have a nonlinear response to the light intensity. This result promises the applicability of PPX-STM measurement to a wide variety of samples. On the other hand, such a nonlinear dependence makes the analysis of the obtained data very difficult. Since the apparent decay time in the signal can be different from the actual value, the analysis must be carried out with detailed knowledge of dependence of the tunnel current on the sample parameter.
