BiSb0.15

BiSb0.15 is a bismuth-antimony alloy semiconductor, likely a bismuth-rich compound with 15% antimony doping or alloying, belonging to the group V semimetal family. This material is primarily of research and specialized industrial interest for thermoelectric applications, where the bismuth-antimony system is valued for its ability to operate effectively at moderate temperatures; it may also find use in niche optoelectronic or infrared detector applications where its narrow bandgap and carrier properties are advantageous. The bismuth-antimony family is notable for thermoelectric performance and thermal-management relevance in situations where conventional semiconductors are unsuitable, though adoption remains limited compared to established thermoelectric compounds like bismuth telluride.
