Quantum Mechanical Improvement of Terahertz Generation by Bloch Oscillators in a Biased Superlattice under a Strong Magnetic Field

Acceso Cerrado

Abstract:

We analyse the effect of a magnetic field parallel to the growth axis of a biased semiconductor superlattice on the amplitude of the terahertz (THz) emission that follows a fast interband optical excitation. We predict a significant increase of the THz emission in the presence of a high field, associated with the freeze out of the in-plane motion of photoexcited carriers.
