The project aims at studying electrons confined in quasi two-dimensional (2D) artificial honeycomb lattices which are specifically designed to generate complex band structures, including Dirac cones and non-trivial flat bands.
The superlattices, which can be seen as artificial graphene materials, will be obtained by turning the 2D electron gas found in conventional III-V semiconductor heterostructures into a triangular antidot lattice at the limit of quantum confinement. Motivated by the interest in finding new types of quantum states which can be manipulated in tunable solid-states devices.
- state-of-the-art low temperature transport measurements will be employed to reveal Dirac fermions and non-trivial band structures predicted in these artificial 2D materials.
- magneto-transport experiments will be used to investigate the complex evolution of the energy bands when magnetic and lattice scales are comparable.
- solid background in solid state/condensed matter physics
- prior experience in low-noise electronic transport techniques, magneto-transport and cryogenics
The position will be at Institut Néel, in close interaction with collaborators in charge of both first-principle calculations and sample fabrication in IEMN, Lille and LCPO, Bordeaux.
