Y. Zohta et al., FREQUENCY-DEPENDENCE OF THE REVERSE-BIASED CAPACITANCE OF BLUE AND GREEN LIGHT-EMITTING-DIODES, Journal of crystal growth, 190, 1998, pp. 816-819
It is found that the capacitance and conductance vs. voltage character
istics of reverse-biased blue and green light-emitting diodes are stro
ngly frequency-dependent. A plausible explanation of this phenomenon i
s proposed that the: shallow acceptor density in the lightly doped p-s
ide is so high that the shallow accepters are not fully ionized near r
oom temperature. (C) 1998 Elsevier Science B.V. All rights reserved.
