Fe-based semiconducting Heusler alloys

详细

A brief overview of the current state of research on Fe-based semiconducting Heusler alloys is given. The most significant achievement in this area is the increase of thermoelectric figure of merit to ZT > 1 in the p-type Fe(V,Nb)Sb-based compounds. Besides these compounds, growing attention has been paid in recent years to the study of promising thermoelectric materials based on Fe₂TiZ (Z = Al, Si, Sn) Heusler alloys and the investigation of multifunctional Fe₂MnZ (Z = Al, Si) compounds, which may be of interest as thermoelectric materials as well as magnetic semiconductors with a high Curie temperature.
