Snake states are trajectories of charge carriers curving back and forth along an interface.
There are two types of snake states, formed by either inverting the magnetic field direction or …

We demonstrate ultrasharp (≲ 10 nm) lateral p–n junctions in graphene using electronic
transport, scanning tunneling microscopy, and first-principles calculations. The p–n junction …

The physical realization of pseudomagnetic fields (PMFs) is an engaging frontier of
research. As in graphene, elastic PMF can be realized by the structural modulations of Dirac …

Confined to a two-dimensional plane, electrons in a strong magnetic field travel along the
edge in one-dimensional quantum Hall channels that are protected against backscattering …

We investigate the superconducting proximity effect through graphene in the long diffusive
junction limit, at low and high magnetic field. The interface quality and sample phase …

The realization of p–n junctions in graphene, combined with the gapless and chiral nature of
its massless Dirac fermions has led to the observation of many intriguing phenomena such …

In graphene, the extremely fast charge carriers can be controlled by electron-optical
elements, such as waveguides, in which the transmissivity is tuned by the wavelength. In this …

We present, for the first time, an atomic-level and quantitative study of a strain-induced
pseudomagnetic field in graphene nanoribbons with widths of hundreds of nanometers. We …

Graphene/two-dimensional (2D) semiconductor heterostructures have been demonstrated
to possess many advantages for electronic and optoelectronic devices. However, there are …
