- 論文の詳細を見る
The data analysis procedure for the time-resolved tunnel current signal obtained by the shaken-pulse-pair method was studied. The fitting function composed of a step function and two double exponential functions that decay from delay time zero towards negative and positive infinities, respectively, reproduced the experimental data. In the analysis, the effects of the interference of the two pulses in a pulse pair, the finite width of impinging pulses, the amplitude of the delay time modulation and the lock-in time constant were considered, for obtaining accurate decay parameters.
