iron, silicon, manganese (for p-type semiconductor) and cobalt (for n-type semiconductor) have been mechanically alloyed using ball mills. These were then compacted into desired dimensions of semiconductor pellets. The pellets were then sintered using inert atmosphere and in vacuum furnace. The sintered pellets were characterized using XRD and SEM.
