Band edges of the separate confinement heterostructure quantum well.
(Color online) Valence-band structure: 15 nm, Al QW.
(Color online) Effective mass of holes (in units of free-electron mass). The solid line: no band mixing; dashed line: 5-nm QW with band mixing; dotted line: 15-nm QW without band mixing.
(Color online) Capture times from 3D HH- state to 2D HH1- state and to 2D HH1 continuous states. Solid line and dotted line: no band mixing; dashed line and dash-dot line: with band mixing.
(Color online) In-plane interaction integrals as functions of normalized in-plane phonon momentum for the 15-nm-wide QW. The diamonds mark the integral values of Al quantum wells. They correspond to different normalized momentum values in a parabolic model and a band mixing model due to different effective mass of hole.
(Color online) Escape times from 2D HH1- state to 3D HH- state. Solid line: no band mixing; dashed line: with band mixing.
