H. Thomas et Jk. Luo, ADMITTANCE SPECTROSCOPY OF DEFECTS IN ELECTRON-IRRADIATED INDIUM-PHOSPHIDE, Semiconductor science and technology, 8(4), 1993, pp. 608-610
Admittance spectroscopic assessment of Au/p-InP structures has reveale
d two new hole defects HD1 and HD2, following 1 MeV electron radiation
of fluence 10(16) cm-2 . These defects were found to be different fro
m the previously reported hole defects H3 and H4, and were responsible
for the removal of most carriers, hence the increase of the series re
sistance and the degradation of solar cell efficiency. The defect HD1
showed a recovery threshold annealing temperature of approximately 70-
degrees-C and was completed by 100-degrees-C after 10 minutes annealin
g. This annealing behaviour corresponded to the recovery of the remove
d carriers.
