Zh. Zhu et al., STUDIES ON THE SYNERGISM OF 3, 4, 9, 10-PERYLENEBIS DICARBOXIMIDE PIGMENTS BY THE DEMBER EFFECT, Dyes and pigments, 21(2), 1993, pp. 105-111
The synergism of 3, 4, 9, 10-perylenebisdicarboximides has been studie
d by Dember photovoltages, the 3, 4, 9, 10-perylenebisdicarboximides b
eing adsorbed on the surface of a p-type silicon semiconductor. It was
found that there exists a capability of hole trapping, regardless as
to whether there is excitation by light or not.
