N-type thermoelectrics of Co-doped iron silicide have been fabricated and studied. The Fe:Co ratio was kept constant at 0.95:0.05 to achieve a composition of (Fe/sub 0.95/Co/sub 0.05/)/sub x/Si/sub 2/, where two values of x were chosen: 0.9 and 0.8 t

While melt-cast FeSi/sub 2/ requires careful heat-treatment of homogenization and phase transformation to achieve thermoelectric /spl beta/-phase, the mechanical alloying(M/A) and sintering method is expected to simplify the process, By using the M/A

Despite high thermoelectric performance, the commercial applications of Bi/sub 2/Te/sub 3/-Sb/sub 2/Te/sub 3/ based thermoelectrics are limited mainly because of production cost due to complicated processing steps. In this study, a new approach to th
