Abstract
The electronic industry needs high quality semiconductor materials in order to realize devices in situations where standard silicon chips cannot work due to expense and geometry. Poor mobility of organic materials has led to the search of new inorganic alternatives i.e. transition metal dichlcogenides. These TX2 (T=Transition metal, X=Chalcogen) are used in diverse applications as catalysts, batteries, lubricants and in fabrication of photoelectrochemical solar cell etc. In light of this realization the present paper reports on the growth of copper doped tungsten diselenide single crystals i.e. CuxWSe2 (x=0, 0.5, 1.0) by direct reaction of the elements using direct vapour transport technique. Transport properties viz. low and high temperature resistivity measurements, high pressure are studied in detail on all these samples. The results obtained and their implications will be discussed in the paper in depth.
