Current research on superconductivity concentrates on coherent nonlocal effects between two normal metals mediated by a superconductor, noise measurements in normal-metal/superconductor heterostructures, the interaction between ferromagnetism and superconductivity on the mesoscopic scale, and superconductivity and the proximity effect in transition metal-dichalcogenides.
Epitaxial complex oxides
We are studying the properties of the interface between LaAlO3 and SrTiO3, which are two band gap insulators. The interface is found to show many interesting phenomena, including the coexistence of superconductivity and magnetism. Our current focus is on interfaces in the (111) crystal orientation, which have properties different from the more extensively studied (001) orientation.
Low temperature scanning probe microscopy
Development of a low temperature, millikelvin range, scanning probe microscope capable of doing atomic force microscopy, magnetic force microscopy and electrostatic force microscopy at temperatures down to 50 mK.
