Total-current spectroscopy of layered rare-metal dichalcogenides under electron excitation

A theoretical interpretation is given of the fine structure in the total-current spectra obtained from the (0001) plane of MoS₂, ZrS₂, and NbSe₂ single crystals. The calculations took into account the energy dependences of band energy-level broadening and of the density of unfilled electronic states which become occupied by electrons entering a solid. The dominant contribution of the bulk band structure to the spectra is demonstrated. Fiz. Tverd. Tela (St. Petersburg) 41, 1875–1878 (October 1999)
