This Report describes the principal results of study |
|
under the US army contract on Dielectric Spectroscopy of |
|
Semiconductors (DSS). Over the last three years, the |
|
following areas of study were pursued: a) time-domain |
|
study of the decay of open-circuit photovoltage in p-n |
|
junctions; b) frequency-domain characterisation of a |
|
variety of p-n junctions on high-resistivity silicon, |
|
including forward-baised junctions; c) frequency-domain |
|
photoconductive measurements on such p-n junctions; and |
|
d) a theoretical study of the significance of the time- |
|
and frequency-dependence of the response of |
|
semiconductors. The results obtained during this contract |
|
consolidate our understanding of the nature of the |
|
trapping and recombination processes which consistently |
|
show fractional power-law dependenced on time instead of |
|
the generally expected exponential dependence. The fact |
|
that the observed time dependence is fully consistent |
|
with that of delayed luminescence adds further incentive |
|
to the development of a general theoretical model for |
|
these processes and one such model is proposed. |
