The quantum Hall effect (QHE), and devices reliant on it, will continue to serve as the
foundation of the ohm while also expanding its territory into other SI derived units. The …

Abstract A three-dimensional (3D) topological insulator (TI) is a quantum state of matter with
a gapped insulating bulk yet a conducting surface hosting topologically protected gapless …

Being a true two-dimensional crystal, graphene possesses a lot of exotic properties that
would enable unique applications. Integration of graphene with inorganic semiconductors …

The quantum Hall effect provides a universal standard for electrical resistance that is
theoretically based on only the Planck constant h and the electron charge e. Currently, this …

We present a new fabrication method for epitaxial graphene on SiC which enables the
growth of ultra-smooth defect-and bilayer-free graphene sheets with an unprecedented …

The study of moiré engineering started with the advent of van der Waals heterostructures, in
which stacking 2D layers with different lattice constants leads to a moiré pattern controlling …

Replacing GaAs by graphene to realize more practical quantum Hall resistance standards
(QHRS), accurate to within 10− 9 in relative value, but operating at lower magnetic fields …

Fractional quantum Hall (FQH) phases emerge due to strong electronic interactions and are
characterized by anyonic quasiparticles, each distinguished by unique topological …

We directly measure the nanometer-scale temperature rise at wrinkles and grain boundaries
(GBs) in functioning graphene devices by scanning Joule expansion microscopy with∼ 50 …

The so-called buffer layer (BL) is a carbon rich reconstructed layer formed during SiC (0001)
sublimation. The covalent bonds between some carbon atoms in this layer and underlying …
