semiconductor quantum well; puits quantique de semi-conducteur
Artificial material consisting of a semiconductor with a low bandgap energy, sandwiched between two semiconductor layers with the same lattice parameter and a higher bandgap energy.
intersubband transition; transition intersousbande
Transition between electronic states confined in a quantum well.
miniband (minigap); miniband (minigap)
Set of allowed (forbidden) electronic states in a set of tunnel-coupled quantum wells. Minibands and minigaps are used in the active region to define the regions in which electronic transport can take place.
cascade effect; cascade mechanism
Mechanism at the heart of quantum cascade laser operation: during laser operation,...
