Abstract
It has been found that the temperature coefficient of resistance of NiCr films deposited on glass is a function of the Ni/Cr ratio. The temperature coefficient of resistance is more negative for films with high Cr content, and a unique composition is possible for which the temperature coefficient of resistance is independent of sheet resistance. The results of using a wide range of alloy compositions are presented and discussed. Methods of depositing these films with a known composition are examined and it is shown that a flash evaporation technique is satisfactory. A suitable design of source is given.Keywords
