Abstract
Structures with real space separate confinement of electrons and holes can cause both
blue- and redshifting of the absorption edge. Such a separate confinemnt can be achieved in a composite well structure, with materials with reverse band offset ratio with respect to the barrier.
We made use of InAsyP1-y and GaxIn1-xAs squantum wells surrounded by InP barriers. Both wells are about 4 nm thick and are separated by 1 nm InP. The structures were grown by Chemical Beam Epitaxy in a p-i-n structure. It was found that an electric field of about 30kV/cm produces a blue shift of 25 meV.
