Reconfigurable Quantum Materials Lab
Cao Lab just turned one! Big thanks to all our incredible members — we couldn’t have done it without you!
Our Research Focus
Cao Lab at UC Berkeley investigates transport phenomena in low-dimensional quantum materials, such as graphene, TMDCs, h-BN, and 2D superconductors, using ultra-low temperatures (<10 mK) and high magnetic fields (>10 T) to reveal exotic states like unconventional superconductivity, the quantum anomalous Hall effect, and correlated many-body phases. We also pioneer lab-on-a-chip platforms, leveraging advanced MEMS to achieve multi-degree-of-freedom control of 2D materials with precision and versatility comparable to scanning probe techniques, but at a fraction of the cost and complexity.

In our recent paper published in Nature, we demonstrated the world’s first micromachine that can twist 2D materials at will.
The fingernail-sized, on-chip platform, called MEGA2D, uses microelectromechanical systems (MEMS) to conduct voltage-controlled manipulation of 2D materials—which are only nanometers thick—with unprecedented flexibility and precision.
Congrats to the team that did the hard works and make this dream come true!
Let us know what you think of this work!
