(a) The schematic model of bilayer graphene with randomly distributed additional bonding interactions between C atoms from top and bottom layers (black-colored carbon atoms). The periodic and fixed boundary conditions were imposed along y and x-directions, respectively. (b) A local arrangement of C-C single bonds and C=C double bonds around one C atom with additional inter-layer bond.
(a) The calculated heat flux in the system by measuring the energy (E) added to the hot bath ( K) and subtracted from the cold bath ( K). (b) The temperature profile of bilayer graphene with 1.5% concentration of inter-layer bonds. The calculated is obtained from the temperature gradient in the linear region.
The calculated of bilayer graphene with respect to inter-layer bond concentration. The results are non-dimensionalized with the thermal conductivity of pristine bilayer graphene () with 0% concentration of bonds.
The power spectra of C atom of PBLG with non-bonding interactions with other layer (red line), and that of IBBLG connected by an bond to other layer (green line). The spectra are also decomposed along in-plane (x and y) and out-of-plane (z) directions (top curves).
The power spectra of C atom of PBLG with non-bonding interactions with other layer (red line) and for C atom in the monolayer graphene (cyan line). The spectra are also decomposed along in-plane (x and y) and out-of-plane (z) directions (top curves).
