The band structure of SnSe2by angle-resolved photoelectron spectroscopy

Abstract
Angle-resolved photoelectron spectroscopy has been applied to study atomically clean surfaces of SnSe2 prepared by cleavage in vacuum. The polar variation of the emission, as well as its dependence on the azimuthal angle, has been measured at room temperature. The results may be easily understood in terms of the band structure of the material and are compared with theoretical calculations.
