“…Heavy p-elements chalcogenides attract a lot of attention of scientists due to their functional properties, such as thermoelectric, photoelectric, optical, magnetic et al properties [1][2][3][4][5][6][7]. Furthermore, despite the toxicity of thallium, complex thallium chalcogenides are closely monitored as topological insulators [6,8,9], Weyl semimetals [10], photo-, X-ray and gamma radiation detectors [11][12][13], as well as thermoelectric materials [4,14,15].…”
