Time- and angle-resolved photoemission spectroscopy for the saddle-point excitons in GaAs

The electronic structure and dynamics of saddle-point excitons formed under E1-resonance excitation around 3.0 eV in GaAs have been studied using time- and angle-resolved photoemission spectroscopy. The momentum- and energy-resolved spectra of the exciton photoionization reveal that the exciton wave...
