Large electropositive cations as surfactants for the growth of polar epitaxial films
Alfred K. C. Cheung, Ilya Elfimov, Mona Berciu +1
Using density functional theory (DFT) we demonstrate that the adsorption of large cations such as potassium or cesium facilitates the epitaxial growth of polar LaAlO (LAO) on S…

Phonon-assisted carrier motion on the Wannier-Stark ladder
Alfred K. C. Cheung, Mona Berciu
It is well known that at zero temperature and in the absence of electron-phonon coupling, the presence of an electric field leads to localization of carriers residing in a single b…
