Experimental proof of Anderson localization in liquid selenium
We measured the electric conductivity of selenium at high temperatures (~2000°C) and at pressures (up to 1000 atm) greatly exceeding the critical values. An abrupt decrease of the electric conductivity of selenium with decreasing density was observed after saturation was reached at the level ~2Χ102Ω_1 cm-1, which corresponds according to Mott's known criterion to the minimal value of the metallic electric conductivity. This behavior of the electric conductivity is a consequence of the Anderson localization of the electrons, a fact confirmed by calculations. A method is proposed for verifying the formulas for the electric conductivity near the mobility threshold and for determining the critical exponent.
