Abstract
We report on the MOVPE growth and characterization of high quality AlGaInAs alloys and their interfaces with InP. The AlGaInAs alloy grown on InP presents a type-II staggered bandgap-lineup interface, for Al alloy composition between 20% and 48%. This interface presents a very intense photoluminescence peak which corresponds to a high efficiency electron-hole pair recombination mechanism. The corresponding 77K interface band gap energy is between 1.1 and 1.2 eV (≈20%
