Research Interests:

My work is almost entirely devoted to experimental studies of the cuprate superconductors. Our group includes, in addition to myself, faculty members D.A. Bonn and J. Carolan, research scientist Ruixing Liang, and research engineer P. Dosanjh. Typically, there are also 1 to 2 postdoctoral fellows, 6-8 graduate students and 2 or so undergraduate students in the group. We interact strongly within the university with Canada Research Chair holder Prof. George Sawatzky, who directs a broad program in nanoscience, and with faculty members Jess Brewer and R. Kiefl, whose active programs in Muon Spin Rotation and Beta NMR at Triumf also encompass the HiTc materials. We also interact with theoreticians Ian Affleck, Philip Stamp, Marcel Franz, and Mona Berciu, part of whose work is also on the HiTc superconductors. Outside of the University, our group maintains collaborative efforts with a number of institutions including SFU, McMaster, University of Toronto, McGill, Stanford University, University of Illinois, Princeton, Berkeley, University of Cambridge, and Los Alamos National Lab.

Our group has heavy concentrations in materials development and microwave measurements. R. Liang grows some of the very best HiTc crystals in the world, and this capability is at the core of both our own work and that of our external collaborations. We also have a laser ablation and sputtering facility for producing thin films, and are beginning work on electric field induced conductivity and superconductivity. We have facilities for magnetic measurements (SQUID magnetometer, magnetic flux imaging) and transport measurements, and, within the AMPEL building, X-ray diffractometry, Scanning Electron Microscopy, Atomic Force Microscopy, cleanroom facilities etc.

Our main research interest is in the microwave and millimetre-wave electrodynamics of the cuprate superconductors, and we have a variety of facilities for precision measurement of magnetic penetration depth and surface resistance over a wide range of temperature (0.3 to 120K) and frequency (from 50MHz to 200GHz). We have particularly concentrated on extracting the intrinsic electrodynamics by the use of very high quality single crystals, with systematic and well-controlled variation of the doping (O, Ni, Zn, Ca), to separate extrinsic from intrinsic behaviour.
