Abstract
Ac (80 Hz) photoconductivity spectral response curves have been measured for seven single crystal samples of Zn3P2 prepared by different preparation techniques and subjected to different heat and surface treatments prior to measurement over the spectral range from 0.6 to 1.2 μm. Surface ac photoconductivity lifetimes range from 0.4 to 40 μsec, and bulk ac photoconductivity lifetimes range from 3 to 100 μsec. Major contributions to the photoconductivity near the band edge of Zn3P2 come from transitions of about 1.41 and 1.52 eV, probably corresponding to direct transitions from the two higher‐lying valence bands split by spin‐orbit and crystal fields.This publication has 13 references indexed in Scilit:
