▎ 摘  要

The analytical two-chain Frenkel-Kontorova model is used to describe domain wall networks in bilayer graphene upon biaxial stretching of one of the layers. We show that the commensurate-incommensurate phase transition leading to formation of a regular triangular domain wall network at the relative biaxial elongation of 3.0 x 10(- 3) is followed by the transition to another incommensurate phase with a striped network at the elongation of 3.7 x 10(-3). The reentrant transition to the phase with a triangular domain wall network is predicted for the elongation similar to 10(-2).
