Ultrafast Hole-Burning in Intersubband Absorption Lines of GaN/AlN Superlattices

Not Accessible

Your library or personal account may give you access

Abstract

Femtosecond two-color pump-probe experiments on intersubband absorption spectra of electrons in a GaN/AlN superlattice show distinct spectral holes unraveling both the homogeneous broadening contribution and the underlying optical phonon progression.
