Jx. Huang et al., ELECTRON TRAPS IN WIDE-GAP N-HG0.3CD0.7TE CHARACTERIZED BY TIME-RESOLVED PHOTOCONDUCTIVITY, Applied physics. A, Solids and surfaces, 57(5), 1993, pp. 427-430
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.
