Some electrical properties of co-evaporated GeO-BaO thin films

  • M. Y. Nadeem
  • C. A. Hogarth


The direct-current electrical conduction both before and after the electroforming process is investigated in thin layers of GeO2 co-evaporated with BaO and sandwiched between various metallic electrodes. The mobility associated with the conduction at low temperature (hopping) is evaluated. Electroformed devices show voltage-controlled negative resistance and electron emission. The effect of the nature of the metallic electrodes and that of the dielectric thickness on these electrical properties is reported.
