Stress produces light-hole exciton

Researchers in Austria, Germany and the Netherlands have succeeded in creating a light-hole exciton ground state by applying tensile elastic stress to a semiconductor quantum dot. The light-hole exciton, which is a quasiparticle formed from a single electron bound to a single light-hole, is very different to the more commonly known heavy-hole exciton and could come in handy for quantum information science and technology applications……
