In the low dimensional electronic lab, we use a variety of measurement techniques to study properties of electrons confined in a unique 2-dimensional environment, the van der Waals materials. Exfoliated with a scotch tape, van der Waals materials consists of one, or few layers of atoms. In this low-dimensional environment, a system of strongly correlated electrons exhibit a wide array of fascinating quantum phases. In addition to various quantum Hall effect phases, we study quantum phases emerging from a moiré lattice induced flat energy band, including superconductivity and ferromagnetism.
In addition to quantum transport measurement, we have developed several new experimental techniques, such as Coulomb screening measurement using the double-layer structure, angle-resolved transport measurement using the “sunflower” geometry, thermodynamics, and resistively-detected electron spin resonance measurements. You can find more details about these exciting techniques in our recent publications.
