Abstract
We report quantitative measurements of the hole dispersion curves of a quantum well using hot-electron-acceptor luminescence in combination with band-edge luminescence. The directionally averaged heavy-hole and light-hole energies are determined for in-plane wave vectors between 3% and 7% of the Brillouin zone. Experimentally significant differences between quantum wells of different widths are observed.Keywords
