Magnesium gallate spinel: A substrate for the direct liquid-phase epitaxial growth of (Ga,Al)As

Abstract

The single-crystal growth of the cubic spinel, MgGa2O 4, by the Czochralski technique is reported. Moreover, experiments are described in which this material is used as a substrate for the first direct (single-step) liquid-phase epitaxial growth of 〈111〉 (Ga,Al)As. © 1972 The American Institute of Physics.
