• Tttnneling spectrtrna observation NV21S carried otnt on 21 Pb(Tl)Te filtn grown by hot-wall epitaxymethod. The observed spectrtmun characteristics on Ag -SiOr -Plo(Tl)Te.junctions reflect a seriesof discrete ener:v levels E. below the conduction band edge Pc, besides the cttmasi localizedTl iuaaptrrity states in the valence band. These discrete energy levels E,. are well expressed byE. - E. O -1.6/n' (n: integer) in eV, and show quite 21 good consistency with the result byEsaki et at," Frotn the investigation using the hydrogen-like ionization rnodel, these donor-likedeejc centers seetn to be re?'tlized only in SLICII 21 highly degener;tied p-type seuaaicondtrctor withthe minor n-type centers in the vicinity of' surf'ace region.
