Native defects in the Co${}_2$Ti$Z$ ($Z=$ Si, Ge, Sn) full Heusler alloys: formation and influence on the thermoelectric properties

Voicu Popescu, Peter Kratzer, Sebastian Wimmer +1

We have performed first-principles investigations on the native defects in the full Heusler alloys Co${}_2$Ti$Z$ ($Z$ one of the group IV elements Si, Ge, Sn), determining their form…
