Correlation of I–V Characteristic with Noise for Ion Drifted p-i-n Junction Particle Detectors

Abstract

This paper describes a technique for achieving minimum noise in a p‐i‐n particle detector. The reverse saturation current of the detector and its relative noise are correlated for different surface treatments. The data show that the reverse current at the detector operating voltage is not a sufficient measure of relative noise. The relative noise can be predicted from the reverse current at two to three times the operating voltage.
