Research Abstract |
In this study, atomistic and electronic structures of nano-structured ferroelectrics (e.g., nano-films and nano-wires) and the coupling effect between mechanical deformation and ferroelectricity, namely, multi-physics properties, have been investigated using rigorous ab initio (first-principles) density-functional theory calculations. We have revealed that the characteristic surface and edge structures of nano-structured ferroelectrics dominate the ferroelectricity, and that f
