GaSb crystals highly doped with tellurium were grown using the Czochralski technique in ionized hydrogen atmosphere. The free-carrier concentration is several times lower than in the case of the use of molecular hydrogen. It has been shown that the ionized atmosphere also acts as a passivator in a wider range of tellurium concentration and that the equilibrium between passivated and active donors is created according to the ratio of p- to n-type dopants in the starting melt.
