L. Zheng et al., INVESTIGATION OF THE TYPE INVERSION PHENOMENA - RESISTIVITY AND CARRIER MOBILITY IN THE SPACE-CHARGE REGION AND ELECTRICAL NEUTRAL BULK IN NEUTRON-IRRADIATED SILICON P-N JUNCTION DETECTORS(), IEEE transactions on nuclear science, 40(4), 1993, pp. 367-375
The changes of effective dopant concentration in the space-charge regi
on (SCR) of neutron irradiated silicon detectors have been investigate
d near the type inversion point. In addition to the conventional capac
itance-voltage(C-V) measurements, transient current technique(TCT) usi
ng a laser light excitation which is absorbed within 10 mum of silicon
was also applied. The details of transient current response in irradi
ated silicon detectors are discussed, which gave the possibility for d
etermining the effective dopant concentration in the SCR as well as pr
operties in the electrical neutral bulk(ENB) of silicon detectors.
