Measured photoresponses for different temperatures and for zero applied voltage and a laser intensity of . In the inset, the number of extracted charge carriers for different applied bias voltages is shown for different temperatures. The dashed lines are fitted guide to the eye lines.
Measured photoresponses for different applied bias voltages and a temperature of . All curves exhibit two distinct changes of slope (kinks) of the current density. The arrows give a guide to the eye for the voltage dependence of the different kinks.
Comparison of simulated and measured photoresponses for different temperatures and the applied bias voltages of and .
Simulated and measured photoresponse for an applied bias voltage of and the temperature . The conduction current densities of the electrons and the holes are given separately. The total current density is composed of the sum of the conduction current densities and the displacement current density. The latter heavily counteracts the strong rise of the conduction current density in the early stages of the photoresponse.
The net detrapping rate of electrons out of the nine different trap states for a bias voltage of and a temperature of . The sum of all contributions is depicted by the thick solid black line.
Set of parameters extracted by fitting the experimental results.
Extracted magnitudes of the characteristic energy from the fitted straight lines of the measured pulse response before and after the transit time at a laser intensity of .
