Abstract
Electrical conductivity of molybdenum disulphide was studied in a helium–sulphur gas mixture as a function of temperature (1073–1273 K). It was found that over the whole temperature and sulphur pressure range (10–6600 Pa) studied, the material exhibits p-type conductivity. Based on literature intrinsic electronic disorder data as well as measured electrical conductivity results a defect model has been proposed. This model involves electron holes and doubly ionized interstitial sulphur ions as majority point defects as well as electrons and acceptor-type foreign ions as minority defects.
