Abstract
Time-resolved photoconductivity measurements have been used to charact erize electron traps in wide-gap n-HgO0.3Cd0.7Te for the first time. T he characterization was made possible by combining the time-resolved p hotoconductive data with the analytical method conventionally used in DLTS spectroscopy. Two electron traps were found in the band gap with 61 meV and 79 meV below the conduction band edge, their concentrations are 1.1 x 10(13) cm-3 and 5.8 x 10(11) cm-3, respectively. Compared w ith DLTS spectroscopy, this characterization method markedly simplifie s sample preparation and experimental procedure.
