Graphene thermal break-down induced by anharmonic bending mode
V. M. Adamyan, V. N. Bondarev, V. V. Zavalniuk
The abrupt loss of mechanical stability of two-dimensional graphene-type crystals at a certain transition temperature is described. At this temperature, the graphene state with pra…

Bending mode and thermal expansion of graphene
Viktor N. Bondarev, Vadym Adamyan, Volodymyr V. Zavalniuk
Proceeding from the model of a two-dimensional elastic continuum, we describe the characteristic features of thermal expansion of graphene using an approach that goes beyond the qu…

Bending sound in graphene: origin and manifestation
V. M. Adamyan, V. N. Bondarev, V. V. Zavalniuk
It is proved that the acoustic-type dispersion of bending mode in graphene is generated by the fluctuation interaction between in-plane and out-of-plane terms in the free energy ar…
