FeSi2
semiconductorIron silicide (FeSi₂) is an intermetallic semiconductor compound that combines iron and silicon, belonging to the family of transition-metal silicides. It is primarily investigated for thermoelectric power generation and waste-heat recovery applications, where its semiconductor properties enable direct conversion of temperature gradients to electrical current. FeSi₂ is notable in this context because it offers good thermal stability, relatively low cost compared to traditional thermoelectric materials, and the ability to operate at moderate-to-high temperatures, making it attractive for automotive exhaust systems and industrial heat recovery where conventional materials may be cost-prohibitive or performance-limited.
