Transport in double-gated graphite devices






Van der Waals technology and a better theoretical understanding (from graphene physics) allowed us to unravel interesting physics even in such an old material as graphite


Twistronics in 3D (graphite)

Aligning graphite with hBN results in topological Lifshitz transitions, Brown-Zak quantum oscillations, and Hofstadter butterfly

ABC (Rhombohedral) graphite: probably the simplest topological insulator with gapped bulk and conducting surfaces! It shows clear signatures of strong electronic correlations – no need for moiré!

2D van der Waals nanocapillaries

2D nanocapillaries enabled by van der Waals technology

Isolated two-dimensional (2D) crystals can be assembled into designer structures layer-by-atomic-layer in a precisely chosen sequence. Using van der Waals (vdW) vdW technology, we have reported the creation of two-dimensional nanocapillary. It can be viewed as if individual atomic planes were pulled out of a bulk crystal leaving an atomically thin void behind (see figure). This technology offers the smallest possible empty spaces that can vary from just a few angstroms in height up to many nanometers on demand.

We will be exploring the nanoconfinement effects based on such nanocapillaries system.



  • Fabricated on a silicon-based substrate, these nanochannels are fully compatible with microfabrication technology, guaranteeing facile integration with different auxiliary units, such as electrochemical cells, microfluidics, spectroscopy, and electronics.

  • Such a system thus presents as a versatile platform to systematically explore both the static (structures and interactions) and dynamic (nanofluidics) behaviors of various molecules under extreme confinement.
