Quantum Device Physics Laboratory


The Quantum Device Physics Laboratory (QDP) performs state of the art research, education, and innovation in the field of nanoscale device physics exploiting the quantized charge and spin degrees of freedom in emerging materials that we tailor down to the atomic scale. Our mission is to develop novel nanoelectronic quantum devices for future generations of information technology, which can be smaller, faster, sensitive, and energy-efficient for a sustainable society.

The research extends over a variety of topics at the forefront of condensed matter physics using nano fabricated devices consisting of emerging 2D materials and van der Waals heterostructures, topological Dirac and Weyl materials, semiconductors, oxide heterostructures, nanomagnets, and superconductors. We combine the best of different materials to develop new concepts in device physics and applications in quantum metrology, topological quantum technology, thermoelectrics, quantum theory, radio astronomy, medical instrumentation, and spintronics.

Nano device fabrication and growth of advanced quantum materials​
We develop nanofabrication processes for making devices in our state-of-the-art clean room facility (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 materials growth reactors, MBE for semiconductor 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.​
