  "abstract": "High-entropy topological insulator (Bi3/4Sb1/4)2(Te2/5Se2/5S1/5)3 has been for the first time prepared by self-propagating high-temperature synthesis and melting methods. Single-crystalline thick-filmed sample with thickness of ~0.1 mm was applied to examine the photoresponse properties by using room-temperature chopped-light technique. Photodetector based on (Bi3/4Sb1/4)2(Te2/5Se2/5S1/5)3 demonstrated strong photovoltaic response under irradiation of a white LED light, covering 420-730 nm range. The photocurrent increases from ~20 to ~55 mkA with the increase in intensity from 100 to 600 W/m2 that is originated from the increase in the number of non-equilibrium carriers generated by light. Room-temperature responsivity and detectivity of the photodetector are ~8.7 mA/W and ~109 Jones, respectively.",
