Thermally stimulated phenomena study in positionally disordered Bi/sub 2/O/sub 3/-PbO system

Thermally stimulated conductivity and thermally stimulated depolarization current measurements have been used to study local states in the forbidden gap of PbO/sub 0/, /spl alpha/-Bi/sub 2/O/sub 3/ and Bi/sub 6/Pb/sub 2/O/sub 11/. The results are discussed in relation to the positional lattice disorder which is a characteristic feature of all the three compounds.
