we have simulated the THz temporal waveforms from narrow-gap semiconductor n-InAs and wide-gap semiconductor n-GaAs.The radiation mechanism for n-InAs is confirmed as the photo-Dember field
and the reason for the higher radiation efficiency of n-InAs than that of n-GaAs is:in the area occupied by the major part of photo-generated carriers
the electric field in n-GaAs is much smaller than that in n-InAs.This reason was not mentioned in all previous studies.
