High resistivity pi-nu-n structures are shown to differ significantly
from traditional drift detectors. It has been found that the amount of
charge formed by a minimum ionizing particle (mip) in these structure
s does not depend on the bias. We consider this phenomenon to be assoc
iated with the relaxation properties of these structures because tau(d
) >> tau(0).
