The authors have studied the unoccupied electronic states of VSe<sub>2</sub> using three different techniques: inverse photoemission spectroscopy (IPES), secondary electron emission spectroscopy (SEES) and target current spectroscopy (TCS). The experimentally determined electron bands are in good agreement with band structure calculations, but on comparison the different techniques reveal significantly different aspects of the conduction band structure. The reasons for these differences are discussed.
