Abstract
We demonstrate hydride vapor phase epitaxy (HVPE) of AlxGa1-xAs, AlxIn1-xP, and AlxGayIn1-x-yP using an AlCl3 precursor. We study the growth of the AlxGa1-xAs alloy system to elucidate the effects of deposition temperature, V/III ratio, and group V precursor species on Al solid incorporation via AlCl3. Crucially, the presence of group V hydride at the growth front kinetically promotes the solid incorporation of Al. We use these insights to demonstrate controlled deposition of AlxGa1-xAs, and for the first time by HVPE, AlxIn1-xP and AlxGayIn1-x-yP. These results create exciting implications for HVPE-grown high-efficiency III-V solar cells and devices with reduced cost.
