Properties of thin oxide films of Cd on glass are studied. Thickness of the films is determined by Strong's method. It was found neccessary to evaporate cadmium over a previously evaporated thin film of chromium to ensure even deposit.
Thin Cd films deposited on glass are found to have exceptionally high electrical conductivity and optical transmission. Heating enhances these properties, irreversively.
As a typical example, Cd film of 5501 in thickness, heated at 300°C, has the specific resistance of 36×10-4Ω. cm and the white-light transmission of 78%. A current of 45 mA through this glass plate (width 2.25cm) raised the temperature of the plate by 60°C (from 5°C).
The film has a possible use as transparent conducting coatings for the purpose of de-icing windows by direct electrical heating.
