Abstract
: Single crystals of Hafnium di selenide (HfSe2) which are a new class of solarcell material have been grown by chemical vapour transport (CVT) technique, with iodine as the transporting agent using a two‐zone horizontal furnace. Electrical resistivity of the grown crystals were measured using two probe and four probe methods. Activation energy of charge carriers were determined. Hall mobility, Hall coefficient and carrier concentrations were also determined. All crystals were found to be of n‐type conductivity. The electrical conductivity, Hall effect and their temperature dependence concludes the characteristic features of the semiconducting properties of these compounds.
