Tellurium Effect on Degradation Stability of Semiinsulating Gallium Arsenide Crystals

Section: Solid matter
Original Author's Text: Ukrainian

Abstract: Initial untreated crystals of semiinsulating tellurium-compensated GaAs are shown to degrade considerably less after HF treatments in comparison with the corresponding specimens doped with chrome, which testifies to a substantial influence of the compensating impurity type on the substance degradation stability. Semiinsulating tellurium-compensated GaAs crystals preliminary treated in hydrogen plasma are also found to have higher degradation stability with respect to the action of long-term high-frequency and microwave treatments in comparison with raw crystals.

Key words: degradation stability of crystals, Czochralski technique, internal mechanical stresses.
