Enhanced thermoelectric power factor in Yb1−xScxAl2 alloys using chemical pressure tuning of the Yb valence

We have investigated the influence of Sc substitution on the transport and magnetic properties of YbAl2, a well-known intermediate valence compound. Sc substitution provides a chemical pressure that decreases the lattice constant and thereby alters the Yb valence as a function of composition and tem...
