GaSb crystals highly doped with tellurium were grown using the Czochralski method without encapsulant in the flowing atmosphere of ionized hydrogen. The inherent free carrier concentration was several times lower than by using the molecular hydrogen. It was shown that the ionized atmosphere served as a passivator in the wider range of tellurium concentration and that the equilibrium between passivated and active donors was created according to the ratio of p- to n-type dopants in the starting melt.
