Research Directions

Nano device fabrication and growth of advanced quantum materials​

Our division develop nanofabrication processes for making devices in our state-of-the-art clean roomfacility​ (area 1240 m2), which provide a broad platform for the development and testing of new ideas in quantum device physics. The material growth facility includes graphene and 2D material​s growth reactors, MBE for se​​miconductor heterostructures and pulsed laser deposition of complex oxides. Our laboratory has facilities with temperature range 300K to 20 mK equipped with low-noise electronics, frequency range DC to THz and magnetic field up to 14 Tesla.

Graphene and Two-Dimensional (2D) Materials Technologies​

We develop graphene and 2D materials-based devices for terahertz detection, quantum metrology, Hall magnetometers, field-effect transistors, and spintronic devices. We further make van der Waals heterostructures of 2D semiconductors and magnetic materials to investigate thermoelectric effects, and spin-orbit & magnetic proximity effects for quantum and spintronic technologies.

Topological Quantum Technologies ​​

We harness the combination of various material classes to engineer novel states of matter, such as topological superconductivity, non-local Andreev states, topological spintronics. We also investigate decoherence sources in engineered quantum devices that are the main obstacle towards achieving an operational quantum computer. Our experiments involve electronic and spin transport, circuit quantum electrodynamics and Josephson radiation spectroscopy.

Spintronics science and technology​

We aim to develop a new spintronics platform where topological effects in Dirac and Weyl materials are combined with spintronic effects for spin-based information storage and processing technolog​ies. Our vision is to exploit the electronic bands of topological materials through Berry curvature design, spin-orbit coupling strength, and tuning time reversal symmetry via magnetic exchange interactions in the heterostructures. We develop spintronic technologies by investigating spin circuits, spin transport and dynamics, creation and control of spin polarized current, novel spin textures, and spin-orbit phenomena such as spin Hall and Rashba-Edelstein effects.

Next-generation detectors for astronomy​

We develop the next generation of detectors for cosmology experiments, using two original concepts: superconductor cold electron bolometer and charge-neutral graphene hot-electron bolometric mixer. Our experiments involve measuements down to sub-Kelvin temperatures in optical cryostats.
