Observation of absorption between split levels in coupled quantum wells

Not Accessible

Your library or personal account may give you access

Abstract

The tunnelling of charge carriers between quantum wells that are separated by a barrier of only a few monolayers thickness leads to a splitting of the energy levels of the quantum wells. Here, we report on the first absorption measurements of the transition between split subbands in the conduction band of coupled quantum wells.
