Application

Bismuth selenide, presented as black crystals with a purity of 99.999% in 1-6mm fused pieces, serves a vital role in the semiconductor industry. Its rhombic and hexagonal structures make it suitable for various applications, despite its decomposition when exposed to air, concentrated nitric acid, or aqua regia. Primarily, it is utilized to produce multilayer thin films and magnetoresistant films, particularly through sputtering targets with 99% or higher purity. These characteristics make bismuth selenide a valuable material in semiconductor and thermoelectric research, offering significant contributions to advancements in these fields.
