Bilayer graphene has a distinctive electronic structure influenced by a complex interplay between various degrees of freedom. We probed its chemical potential using double bilayer graphene heterostructures, separated by a hexagonal boron nitride dielectric. The chemical potential has a nonlinear carrier density dependence and bears signatures of electron-electron interactions. The data allowed a direct measurement of the electric field–induced bandgap at zero magnetic field, the orbital Landau level (LL) energies, and the broken-symmetry quantum Hall state gaps at high magnetic fields. We observe spin-to-valley polarized transitions for all half-filled LLs, as well as emerging phases at filling factors ν = 0 and ν = ±2. Furthermore, the data reveal interaction-driven negative compressibility and electron-hole asymmetry in N = 0, 1 LLs.

The Way

“The chemical potential for a semiconductor” deals with the way in which the chemical potential (Fermi level) of a semiconductor is affected: by the densities of states in the bands; by temperature; and by doping. The electron–hole product is usually independent of doping but sensitive to temperature. The chemical potential is worked out numerically for an example case, and is shown to be most sensitive to doping.
