Graphene monolayer was the first solid-state material to show a linear dispersion relation
around the corners of the first Brillouin zone. This unusual dispersion relation led to specific …

We explore higher-order topological superconductivity in an artificial Dirac material with
intrinsic spin-orbit coupling, which is a doped Z 2 topological insulator in the normal state. A …

Imposing an external periodic electrostatic potential to the electrons confined in a quantum
well makes it possible to engineer synthetic two-dimensional band structures, with electronic …

Gate voltages take full advantage of 2D systems, making it possible to explore novel states
of matter by controlling their electron concentration or applying perpendicular electric fields …

Ferroelectric photovoltaic cells have attracted particular interest owing to their potential
applications in the green energy field. But there are two drawbacks: weak polarization and …

Semiconductor quantum-dot (QD)-based artificial graphene (AG) is of great interest thanks
to its innovative properties associated with the honeycomb topology, the many-body effects …
