Solid State Communications 11(9): 1131-1134.0038-1098http://nrs.harvard.edu/urn-3:HUL.InstRepos:9962001The photoconductivity spectra of high purity, semiconducting CdF2, containing low concentrations of rare-earth donors, are interpreted in terms of a shallow trap \(1260 \pm 100cm^{-1} \) below the bottom of the conduction band and an excited bound state \(1030cm^{-1} \) above the ground state.en-USJournal Article10.1016/0038-1098(72)90808-3
