Off-stoichiometric variable doping for exceptional power factors in L2${}_1$ Fe${}_2$VAlM${}_x$ (M=Ti, W) epitaxial thin films

Jose María Domínguez-Vázquez, Miguel Angel Tenaguillo, Ketan Lohani +7

We show that the addition of Ti or W to stoichiometric L2${}_1$ Fe${}_2$VAl thin films by sputter codeposition produces off stoichiometric thin film alloys with superior thermoelectric…
