Abstract:

Controllable electronic energy band tails have been prepared in heavily doped, closely compensated GaAs. Their properties are found to correspond in many ways with the reported properties of amorphous semiconductors. The control now over the occupation of the band tail states permits observation of the energy dependence of various transport properties, temperature dependence of the d.c. conductivity, frequency dependence of the a. c. conductivity and current-voltage relations. Possible applications are discussed. The electronic properties of Fe3O4 and VO2 are also studied. The possibility of switching due to dissociation of polarons was examined theoretically as well as experimentally using oxygen-reduced TiO2.
