Description:
Author(s): Yan-Feng Lao, A. G. Unil Perera, L. H. Li, S. P. Khanna, E. H. Linfield, and H. C. Liu We employ internal photoemission spectroscopy to directly measure the valence-band Van Hove singularity, and identify phonons participating in indirect intervalence-band optical transitions. Photoemission of holes photoexcited through transitions between valence bands displays a clear and resolvable... [Phys. Rev. B 88, 201302] Published Mon Nov 11, 2013
