Theoretical prediction and experimental realization of TaFeSb half-Heusler. a Phase stability diagram for TaFeSb, where each line represents a known competing phase and the stable region is indicated in violet. It should be noted that \(\Delta \mu _{{\mathrm{Fe}}}\) and \(\Delta \mu _{{\mathrm{Ta}}}\) are both negative. b) Calculated phonon dispersion of TaFeSb. c Rietveld refinement for the XRD pattern of the prepared TaFeSb in this work. d The [111] zone-axis selected area electron diffraction pattern
