Single crystals Ti0.9Cr0.1(Se0.8S0.2)2 and Ti0.85Cr0.15(Se0.8S0.2)2 were synthesized for the first time by gas-transport reactions. The structural and phase purity of the obtained single crystals was investigated by X-ray powder diffraction. The chemical composition of the synthesized samples was determined by energy dispersive X-ray spectroscopy on a scanning electron microscope. The electronic structure was studied by ARPES method. With increasing Cr concentration, a decrease in conduction band filling and a decrease in hole mass is observed. The absence of dispersion-free band is also observed, which indicates the absence of metal intercalation into the interlayer space. Keywords: janus structures, angle-resolved photoemission spectroscopy, transition metal dichalcogenides.
