摘要：
The growth of mixed tungsten sulphoselenide single crystals i.e. WSxSC2-x (0 <= x <= 2) grown by vapour phase technique and their characterization by Hall effect and thermoelectric power measurements have been reported. The Hall effect measurement indicates that these crystals are p-type in nature, which is very well supported by thermoelectric power measurements. From the temperature dependence of thermoelectric power, the Fermi energy.(E-F) and the constant (A) indicating the nature of scattering process have been obtained for all the samples. The density of states (N-A) and effective mass of holes (m(h)*), have also been calculated for WSxSe2-x samples.
