Transition and switching properties of the blue potassium molybdenum bronze thin films

Abstract

Blue potassium molybdenum bronze (BPMB) bulk material was usually prepared by electrolytic reduction of K 2 M o O 4 -M o O 3 melts. We propose a new method for preparing BPMB film by the simultaneous vacuum evaporation of potassium molybdate and molybdenum trioxide. The ratio of K/M o in compound was obtained from the energy-dispersive spectrum. The transition and switching properties of mixed film with sandwich structure were measured. The results of the measurements reveal the metal-semiconductor transitions behavior in the temperature region of 165-180 K. The switching characteristic of the sandwich structure was achieved.
