As the dimensions of a material shrink from an extended bulk solid to a nanoscale structure,
size and quantum confinement effects become dominant, altering the properties of the …

In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

Electrons transmitted across a ballistic semiconductor junction are expected to undergo
refraction, analogous to light rays across an optical boundary. In graphene, the linear …

Van der Waals interactions with transition metal dichalcogenides were shown to induce
strong spin-orbit coupling (SOC) in graphene, offering great promises to combine large …

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 …

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 …

The electron microscope has been a powerful, highly versatile workhorse in the fields of
material and surface science, micro and nanotechnology, biology and geology, for nearly 80 …

In this paper, we present a method for generating a synthetic gauge field in the vertical
direction by linearly modulating the mass term in a Dirac equation model. This allows for the …

We put forward a concept to create highly collimated, nondispersive electron beams in
pseudorelativistic Dirac materials such as graphene or topological insulator surfaces …
