In-House Facilities
Riber molecular beam epitaxy system used for quantum-material thin-film growth.
Molecular Beam Epitaxy
Our MBE laboratory is used to synthesize oxide heterostructures, rare-earth intermetallic thin films, and magnetic quantum materials. The system supports fully computer-controlled growth using predefined deposition sequences, enabling reproducible control of complex growth and annealing protocols. The growth chamber routinely reaches a base pressure below 2×10−10 Torr, maintained by a combination of cryogenic, high-compression turbomolecular, and ion pumping. In situ RHEED provides real-time feedback on surface structure and growth, enabling control of crystalline orientation, phase formation, and interface quality.
Oxford TeslatronPT cryogenic transport system for low-temperature, high-field measurements.
Low-Temperature Quantum Transport
We perform cryogenic electrical transport measurements to investigate superconductivity, magnetotransport, nonlinear response, and symmetry-dependent electronic phenomena. Our measurement platform combines high magnetic fields, low temperatures, precision low-noise electronics, flexible sample rotation, and wire-bonded device integration for angle-dependent and low-signal transport studies.

Omicron scanning probe microscopy system for surface characterization of quantum-material thin films.
Surface & Materials Characterization
We use scanning probe and surface-analysis techniques to characterize thin-film morphology, surface structure, and electronic properties. These measurements provide feedback on growth quality and help connect synthesis conditions with the microscopic properties of quantum-material thin films and heterostructures.
PHI VersaProbe 5000 XPS system
We use X-ray photoelectron spectroscopy to probe surface composition, chemical states, and oxidation-state changes in quantum-material thin films and heterostructures, providing a direct connection between synthesis conditions and electronic properties.
