▎ 摘  要

The commensurability condition is applied to determine the hierarchy of fractional filling of Landau levels for fractional quantum Hall effect (FQHE) in monolayer and bilayer graphene. The difference in FQHE hierarchy for bilayer and monolayer graphene is outlined and explained. Good agreement with experimental data is achieved. The presence of even-denominator filling fractions in the hierarchy of the FQHE in bilayer graphene is explained, including the state at nu = -1/2. (C) 2015 Elsevier B.V. All rights reserved.
