Abstract:

The worldwide scientific quest for an understanding of the switching phenomenon in amorphous semiconductor films faced a controversy as to whether it was a thermal or electronic process. A practical concern about the stability of chalcogenide switching devices prompted switching studies in the more stable oxides. These include oxides from the Bi2O3.ZnO.MnO ternary system and the V2O5.P2O5 binary. A basic study compared the electronic spectra, structures, and electrical characteristics of several crystalline and noncrystalline semiconductors. A new technique for the preparation of oxide films was developed.
