Transport, Dielectric and Switching Properties of Transition Metal Oxides.

Abstract

Transport mechanisms in amorphous films of transition metal oxides and polycrystalline films of CoO, CoO(Li), Nb2O5, and TiO2 are of the Poole-Frenkel or Poole Effect type. In NiO and NiO(Li) films the transport mechanism is explained by the small-polaron conduction. Dielectric dispersion is due to the non-adiabatic hopping of charge carriers at low frequencies and adiabatic hopping at high frequencies. A novel type of switching is observed with switching, delay and recovery times of less than 3 nsec in Nb-Nb2O5-Nb with sputtered Nb counterelectrodes.
