Proposal of a one-dimensional electron gas in the steps at the LaAlO-SrTiO interface
N. C. Bristowe, T. Fix, M. G. Blamire +2
The two-dimensional electron gas (2DEG) at the interface between LaAlO (LAO) and SrTiO (STO) has become one of the most fascinating and highly-debated oxide systems of rece…
Electrochemical ferroelectric switching: The origin of polarization reversal in ultrathin films
N. C. Bristowe, Massimiliano Stengel, P. B. Littlewood +2
Against expectations, robust switchable ferroelectricity has been recently observed in ultrathin (1 nm) ferroelectric films exposed to air [V. Garcia , Nature {\bf 460},…
The net charge at interfaces between insulators
N. C. Bristowe, P. B. Littlewood, Emilio Artacho
The issue of the net charge at insulating oxide interfaces is shortly reviewed with the ambition of dispelling myths of such charges being affected by covalency and related charge…
