Two-color femtosecond spectroscopy of large-momentum excitons in GaAs

Not Accessible

Your library or personal account may give you access

Abstract

It is usually assumed that first-order interband transitions in crystalline solids occur almost vertically in the band structure since the photon momentum is negligible compared to the reciprocal lattice vector.
