Abstract
Abstract The electrical discontinuity which appears in the temperature response of certain materials when they are in crystalline form and are at characteristic transitional temperatures is suppressed by depositing the material on a substrate which is maintained at a temperature low enough to cause the resulting film to be amorphous. Also, by utilizing temperatures on either side of the transitional temperature, for example, new and different resistivity versus temperature responses may be realized which do not inhibit the semiconductor-metal transition.
