Abstract

MnO₂ thin films have been prepared by thermal evaporation technique onto glass substrate at varying deposition pressure. Electrical studies of the films deposited at about 1.5 X 10^-5 Torr show a positive TCR indicating metallic characteristics, whereas a negative TCR indicating semiconducting behavior exhibit on the films deposited at a pressure of about 3.0 X 10^-6 Torr. Thickness dependent electrical conductivity, activation energy, and aging effect were also carried out. Optical measurements in the wavelength range 0.3 < (lambda) < 2.5 micrometers show the films highly transparent in the visible. These studies may be of importance for the application of this material in surface coating for energy efficient devices.
