Abstract:We have studied the transport properties in metallic n-type InP semiconductor. We
show that the dependence on temperature of metallic electrical conductivity obey to the law π = π(π = 0) + ππ1/2. We highlight the absence of a minimum electrical conductivity ππππ proposed by Mott at the metal-insulator transition. We show that the conductivity at temperature T = 0 K, π(π = 0) , follows a scaling law as a function of the effective parallel and perpendicular Bohr radii πβ₯ and πβ₯.
