Enhancement of intrinsic photoluminescence due to lateral confinement in InP/InGaAs quantum wires and dots

Abstract
Low-temperature photoluminescence and photoluminescence excitation experiments have been performed on lattice-matched InGaAs/InP quantum wells, wires, and dots grown by metalorganic vapor-phase epitaxy and processed by electron-beam lithography. An enhancement of the intrinsic photoluminescence mechanism is found with decreasing dimensionality.
