In this paper, numerical analysis techniques are applied to the study of mi
crostrip silicon detectors exploited in the field of high-energy physics. A
t high luminosity required by future experiments, radiation hardness of suc
h device becomes a critical issue. The adoption of relatively low-resistivi
ty substrates has been suggested as a key to face such a problem: simulatio
ns have been carried out to verify this assumption. Comparisons have been m
ade in terms of depletion voltage, as well as of charge-collection efficien
cy, by exploiting some of the features of a customized simulation environme
nt. Estimated, long-term radiation hardness of low-resistivity detectors fa
vorably compares with high-resistivity ones. (C) 2000 Elsevier Science B.V.
