Strain enhancement of high-k dielectric response in (La/Sc)2 O3 and LaScO3 : an ab-initio study

Stas M. Avdoshenko, Alejandro Strachan

We use density functional theory within the generalized gradient approximation to characterize the dielectric response of rare earth oxides: (La,Sc)2 O3 bixbyite, and LaScO3 perovs…
