Abstract :
Photoluminescence experiments on strained InAs0.48P0.52InP quantum wires show that the wire-width-dependent blue shift of the transition energy is much larger than the blue shift in lattice matched quantum wires. With magneto-luminescence measurements we are able to prove that lateral confinement effects only partly explain the observed blue shift. The other contribution comes from the strain energy which is wire width dependent in spite of a constant lattice-mismatch
