My group’s research combines high purity crystal growth with two very different forms of spectroscopy: measurements at microwave frequencies, which measures bulk electronic properties, and scanning tunneling spectroscopy, which measures electronic properties down at the atomic scale. The crystal growth activity is the cornerstone of our work, supplying samples for our own measurements as well as numerous collaborations within the SBQMI and with our partners. In the past year, a network of collaborators using our crystals of high-temperature superconductors have been accessing a wide range of international facilities to uncover, in very high magnetic fields, the charge density wave order that competes with superconductivity in these materials. Our in-house measurements have turned mainly to the newer family of exotic superconductors – the iron-based compounds. A combination of microwave spectroscopy and scanning tunneling spectroscopy is being used to identify the superconducting gap structure in the simplest of these materials, FeSe.
