## Description

- description: In bilayer graphene, electrostatic confinement can be realized by a
    suitable design of top and back gate electrodes. We measure electronic transport
    through a bilayer graphene quantum dot, which is laterally confined by gapped
    regions and connected to the leads via p-n junctions. Single electron and hole
    occupancy is realized and charge carriers n = 1, 2, . . . 50 can be filled successively
    into the quantum system with charging energies exceeding 10 meV. For the lowest
    quantum states we can clearly observe valley and Zeeman splittings with a spin
    g-factor of gs ≈ 2. In the low field-limit, the valley splitting depends
    linearly on the perpendicular magnetic field and is in qualitative agreement with
    calculations.
