Chalcogenide Semiconductor Thin Films

In general, the conductivity-temperature curves of impurity semiconductors should be affected by the rate of heating. An arrangement is described by which such curves can be recorded with rates of heating up to 5,000 centigrade degrees per second. Extensive tests made on lead sulphide films in an oxygen atmosphere lead to conclusions about the stages of oxidation.
