Using the tight-binding model, we have studied the impact of AA and AB (Bernal) stacking on eigenstates and eigenvalues of bilayer graphene nanoflakes with triangular geometry. The zero eigenvalues of any single layer nanoflake will be doubled through AB stacking. However, we have noticed that...

The controversial AA stacking found experimentally [Algara-Siller, Nature (London)519, 443 (2015)NATUAS0028-083610.1038/nature14295] is consistent with our minimum-energy crystal structure of bilayer ice. Furthermore, we predict that an odd number of layers of ice has the same lattice structure ...
We have systematically investigated the effects of lithium (Li) on AA and AB stacking sequences of bilayer graphene using density functional theory (DFT). To accurately describe the bonding that occurs in bilayer graphene, the following van der Waals corrected exchange correlation functionals were use...
Stacking structures at temperatures below 2,600 °C may be deter- mined by the migration kinetics of the graphene planes. The analysis is supported by energy consideration shown in Fig. 6a. AA' stacking exists in a local potential well in the energy landscape, although AB stacking is ...

A comparison of AABG andAB-stacked bilayer graphene (BBG) demonstrates that the optical properties are dominated by the stacking symmetry. The presented results could offer a way to distinguish AABG from BBG and monolayer graphene. 展开
3. Perform a soft body impact simulation of fibre metal laminates with different metal thicknesses and stacking sequences (Section 4.3). 4. Compare the impact responses (reaction force, deflection, and energy) and damage behaviours (metal failure, matrix failure, fibre failure and delamination) ...
