| Abstract: | The growth of mixed tungsten sulphoselenide single crystals
i.e. WSxSe2-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 (EF) and
the constant (A) indicating the
nature of scattering process have been obtained for all the samples. The
density of states (NA) and
effective mass of holes (m*h), have also been calculated for WSxSe2-x
samples. |
