WebAn ultrahigh refractive index of up to 5.9 was observed in the Bi 2 Te 3 thin film in near-infrared frequency. The refractive index dramatically decreases by a factor of ~3 by an exposure to the 800 nm femtosecond laser beam. Simultaneously, the transmittance of the Bi 2 Te 3 thin films markedly increases to ~96% in the near-infrared frequency.

Web20. feb 2024 · The topological insulator of Bi 2 Se 3 -Bi 2 Te 3 heterostructures were synthesised by two-step reaction proceeding. The reaction arised in two steps: at first, Bi 2 Se 3 nanosheets were prepared in the solvent of ethylene glycol (EG); secondly, Bi 2 Te 3 was epitaxial grown on the Bi 2 Se 3 nanosheets to form heterostructure materials. WebBismuth telluride (Bi2Te3), also known as bismuth(III) telluride, is a grey solid powder with a crystalline structure in its pure form. While it occurs in nature as the mineral tellurobismuthite, it is typically prepared by heating elemental bismuth and tellurium under vacuum in a muffle furnace.
