AbstractA ±100 V square wave applied to a Au/semi-insulating SI-GaAs interface was used to bring about electron emission from and capture into deep level defects in the region adjacent to the interface. The electric field transient resulting from deep level emission was studied by monitoring the positron drift velocity in the region. A deep level transient spectrum was obtained by computing the trap emission rate as a function of temperature and two peaks corresponding to EL2 (E a=0.81±0.15 eV) and EL6 (E a=0.30±0.12 eV) have been identified. © 2002 American Institute of Physics.
