Abstract
Intersubband relaxation time for InxGa1-xAs/AlAs multiple quantum wells presenting a large transition energy (680 meV) is measured by means of pump and probe experiments. Differential transmission decays in about 10 ps. The possible influence of intrasubband relaxation and Γ–X coupling on intersubband decay is discussed.File in questo prodotto:
