Two-phonon scattering in graphene in the quantum Hall regime
One of the most distinctive features of graphene is its huge inter-Landau-level splitting in experimentally attainable magnetic fields which results in the room-temperature quantum Hall effect. In this paper we calculate the longitudinal conductivity induced by two-phonon scattering in graphene in a...

oai:animorepository.dlsu.edu.ph:faculty_research-52732022-07-05T05:52:26Z Two-phonon scattering in graphene in the quantum Hall regime Alexeev, Arseny M. Hartmann, Richard R. Portnoi, Mikhail E. One of the most distinctive features of graphene is its huge inter-Landau-level splitting in experimentally attainable magnetic fields which results in the room-temperature quantum Hall effect. In this paper we calculate the longitudinal conductivity induced by two-phonon scattering in graphene in a quantizing magnetic field at elevated temperatures. It is concluded that the purely phonon-induced scattering, negligible for conventional semiconductor heterostructures under quantum Hall conditions, becomes comparable to the disorder-induced contribution to the dissipative conductivity of graphene in the quantum Hall regime. © 2015 American Physical Society. 2015-11-30T08:00:00Z text https://animorepository.dlsu.edu.ph/faculty_research/4459 info:doi/10.1103/PhysRevB.92.195431 Faculty Research Work Animo Repository Graphene Quantum Hall effect Physics |
