Elemental diffusion and reactions at interfaces significantly increase resistivity and reduce stability, particularly in thermoelectric (TE) systems containing highly diffusive elements like Te. Using thermodynamically stable phases as contact layers have eliminated interfacial reactions but have not been able to completely stop elemental diffusion. This work introduces an innovative approach to effectively increase the activation energy of cross-interface atom diffusion by creating a continuously interfacial symmetric strain field via a high d...
