WebBismuth telluride (Bi 2 Te 3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth(III) telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bi 2 Te 3 is a topological insulator, and thus exhibits thickness … WebOct 15, 2024 · A stable photodetector was fabricated with pristine and alloyed nanocrystals where the best performance was achieved for Cs 3 Bi 2 I 9. The functionality in the form of a fast photodetector suggests that these Cs 3 Bi 2 Br 9 (1–x) I 9x nanocrystals are prospective optoelectronic materials.
