DC electrical conduction in heat-treated poly nickel phthalocyanine

Abstract

Heat treatment of poly nickel phthalocyanine leads to a charge transfer and hence there is an improvement in conductivity by 5 orders of magnitude. DC electrical conductivity measurements have been carried out in the heat-treated samples in the temperature range 270 K-10 K. Mott's variable range hopping conduction in one dimension is observed in the temperature range 270K-77 K and the conductivity remains constant in the temperature range 77 K-10 K.
