title = "Light effective mass in the widely-dispersed valence band of single crystalline rubrene observed by high-resolution angle-resolved ultraviolet photoelectron spectroscopy",
abstract = "High-resolution angle resolved ultraviolet photoelectron spectroscopy measurements were conducted on rubrene single crystals assisted by a laser illumination resulting in successful relief of the sample charging. Significant dispersion of the valence band was clearly resolved. The band width W and the hole effective mass mh were estimated to be 0.4 eV and 0.65mo, respectively, along the most conductive direction. The present results strongly suggest that the transport nature in rubrene single crystals should be described in the band transport of a delocalized charge carrier.",
