Abstract
The galvanomagnetic effects in the n-Pb1-xGexTe (x=0.02-0.13) alloys, doped with chromium, at the temperatures in the range of 4.2≤T≤300 K and under hydrostatic compression of up to 17 kbar have been investigated. The insulator-metal transition, induced by pressure in Pb1-xGexTe: Cr (x=0.10) alloy, was revealed. Using the experimental data in the frame of two-band Kane dispersion relation the pressure dependences of electron concentration and Fermi energy were calculated. The pressure coefficient of chromium deep level energy was obtained and the diagram of the electronic structure reconstruction under pressure was proposed.
