Piezoelectricity in half-Heusler narrow-bandgap semiconductors
{{output}}
Piezoelectricity is primarily observed in noncentrosymmetric insulators or wide bandgap semiconductors. We report the observation of the piezoelectric (PE) effect in half-Heusler (HH) narrow-bandgap semiconductors TiNiSn, ZrNiSn, and TiCoSb. These materials ex... ...
