Materials science: Clear leap for superconductors
Darrell G. Schlom1 & Charles H. Ahn2
Abstract
Electric fields offer an innovative means of controlling condensed-matter systems. The approach has been applied to nanoscale oxide interfaces, for studying the physics of two-dimensional superconductors.
In recent years, the ability to engineer the interface between two oxides on the nanoscale with atomic-layer precision has led to remarkable advances in our knowledge of the electronic phenomena occurring at these interfaces. For instance, the transfer of charge at the interface between two ordinary oxide insulators, LaAlO3 and SrTiO3 (ref.
