Pulsed admittance spectroscopy

摘要

A new method of assessing the capture cross section of deep centers is described. The pulsed admittance spectroscopy technique is essentially an admittance spectroscopy experiment fed with electrical pulses. The main features are simplicity and extended range of available time constants (10-8–10-3 s). Experimental results are presented concerning gold and copper impurities in CdTe.
