Growth of InAsxP1−x/InP multi-quantum well structures by solid source molecular beam epitaxy

Abstract
We report on the growth of high quality pseudomorphic InAsxP1−x/InP single and multi‐quantum well (MQW) structures by solid source molecular beam epitaxy, using valved cracker sources to accurately control the group V ratio. A series of MQW’s grown in a pin configuration covering the 1.0–1.30 μm wavelength showed intense narrow room temperature photoluminescence (PL) and extremely narrow 10 K PL linewidths (≤8 meV). Devices fabricated from these structures exhibited low reverse dark currents (xP1−x/InP for optoelectronic devices in this wavelength range.
