Webbismuth (Bi), the most metallic and the least abundant of the elements in the nitrogen group (Group 15 [Va] of the periodic table). Bismuth is hard, brittle, lustrous, and coarsely crystalline. It can be distinguished from all other metals by its colour—gray-white with a reddish tinge. History WebBinary Compound Bismuth Sulphide (Bi2S3)are narrow band gap semiconductor with layered structure and are interesting and important because of major contribution in solar cells, photo detectors, Opto-electronic light amplifiers, Lasers, photo electronic cells. Thin films are grown by chemical bath deposition, chemical vapor Deposition technology.

WebBismuth selenide is a semiconductor and a thermoelectric material. [4] While stoichiometric bismuth selenide should be a semiconductor with a gap of 0.3 eV, naturally occurring selenium vacancies act as electron donors, so Bi 2 Se 3 is intrinsically n -type. [5] [6] [7] Bismuth selenide has a topologically insulating ground-state. [8] WebBismuth, the woman said, it casts really well and it's a lot less toxic than lead. I left the shop with a bag of that as well. Bismuth is without doubt a heavy metal; It occurs so low in the periodic table many were puzzled by the fact that it didn't seem radioactive. In fact its major isotope bismuth-219 was predicted to be so back in 1949.
WebThe convergence of multivalley bands is originally believed to be beneficial for thermoelectric performance by enhancing the charge conductivity while preserving the Seebeck coefficients, based on the assumption that electron interband or intervalley scattering effects are totally negligible.
