On the quantum magnetic oscillations of electrical and thermal conductivities of graphene

• Influence of crossed fields on the oscillating conductivities of graphene.
• It is possible to control the quantum oscillations by managing the electric field.
• It was possible to increase the absolute value of conductivities.

Oscillating thermodynamic quantities of diamagnetic materials, specially graphene, have been attracting attention of the scientific community due to the possibility to experimentally map the Fermi surface of the material. These have been the case of the de Haas–van Alphen and Shubnikov–de Haas effects, found on the magnetization and electrical conductivity, respectively. In this direction, managing the thermodynamic oscillations is of practical purpose, since from the reconstructed Fermi surface it is possible to access, for instance, the electronic density. The present work theoretically explores the quantum oscillations of electrical and thermal conductivities of a monolayer graphene under a crossed magnetic and electric fields. We found that the longitudinal electric field can increase the amplitude of the oscillations and this result is of practical and broad interest for both, experimental and device physics.
