Possibility of Anderson transition in liquid Se and As in the region of high temperatures and pressures

Abstract Conductivity of selenium and arsenic at high temperatures, 2000°C, and supercritical pressures has been measured. With the density decrease the conductivity was found to drop rapidly from the ∼ 10 2 Ω −1 cm −1 level corresponding to the minimal conductivity estimated by Mott. This is accounted for by the Anderson localization of electrons and confirmed by the calculations presented.
