Abstract

We report the epitaxial growth of zinc-blende BxGa1 - x - y InyAs and BxGa1 - xAs on GaAs substrates with boron concentrations (x) up to 2%-4% by atmospheric-pressure metalorganic chemical vapor deposition. The band gap of BxGa1 - xAs increases by only 4-8 meV/%B with increasing boron concentration in this concentration range. We demonstrate an epitaxial BxGa1 - x - yIny,As layer deposited on GaAs with a band gap of 1.34 eV that is significantly less strained than a corresponding Ga1 - yInyAs layer with the same band gap.
