| Popis: | Quantum oscillations of metallic systems at low temperatures is one of the key rules to experimentally access their electronic properties, such as energy spectrum, scattering mechanisms, geometry of Fermi surface and many other features. The importance of these knowledge is enormous, since from these a thorough understanding of anomalous Hall effect, thermopower and Nernst coefficients, just to name a few, is possible; and from those knowledge, a plenty of applications arise as emerging technologies. In this direction, the present contribution focus on a complete description of quantum capacitance oscillations of monolayer and bilayer graphenes under crossed electric and magnetic fields. We found a closed theoretical expression for the quantum capacitance and highlight their amplitude, period and phase - important parameters to access the electronic properties of graphenes. These results open doors for further experimental studies. Comment: 5 pgs and 2 figures |
