Abstract
Angular-resolved photoelectron spectra (ARPES) are presented for GeS using 21-eV excitation energy. From the measurements that cover a wide range of angles along the two principal directions in the basal plane of the orthorhombic layered compound GeS vs curves were constructed. The band structure of GeS was calculated utilizing the empirical pseudopotential method. The vs curves can almost completely be understood in terms of this band structure under the assumption that only peaks in the one-dimensional density of states along contribute significantly to the ARPES spectrum.
