Solid-State Spectroscopy Facilities

The solid-state spectroscopy laboratory is equipped with a range of laser sources and cryogenic equipment for performing spectroscopy of solids. There are a number of dye-laser systems, having wavelength tuneable over a wide range, and offering sub-kilohertz resolution by locking to an external reference cavity. There is a nitrogen pulsed laser pump available for low-resolution spectroscopy, and a diode laser system operating at telecom wavelength. There is a range of cryostats available, including continuous flow, bath, and bucket designs. All cryostats have optical access, and magnetic fields up to 15 T can be applied to the sample using superconducting magnets. A continuous flow cryostat is utilized in a confocal setup to allow for single site detection. Bulk crystalline samples can be grown in the crystal-growing laboratory. The crystals can be grown from solution, or using a high temperature induction furnace. There is also access to a range of fabrication and characterization facilities. For fabrication, this includes a pulsed laser deposition system for epitaxial growth, photolithography and plasma etching. For characterization, the available equipment includes a Raman spectrometer, atomic-force microscope, optical profiler, and X-ray diffraction and electron paramagnetic resonance systems. The research efforts are further supported by the Research School of Physics and Engineering facilities. This includes access to cryogenic liquids, including helium recovery and on-site liquification.
