Using first-principles methods, we show that an applied perpendicular electric field E breaks the inversion symmetry of AB-stacked bilayer graphene (BLG), thereby slightly mixing the two in-plane high-energy optical vibrations (Eand Emodes). The mixed amplitudes increase parabolically with respect ...

Raman characterization of AB- and ABC-stacked few-layer graphene by interlayer shear modesdoi:10.1016/j.carbon.2015.11.062Stacking order of layered materials strongly influences their electronic properties. Bernal (AB) and rhombohedral (ABC) stacking are much common in few-layer graphenes. Here, we...
Monolayer graphene (1LG) has received intensive interest because of its unique properties [1], [2], [3], [4], [5] which provide the impetus for potential applications as electronic and photonic devices. 1LG can be stacked vertically to form N layer graphene (NLG, N > 2) with distincti...
Similarly, whereas the most stable structures of the two-adatom systems Ni2/GNR, Ru2/GNR, Rh2/GNR, and Pd2/GNR had the adatoms above two neighboring edge bays, Co2/GNR and Pt2/GNR were most stable with the adatoms stacked in a double-decker configuration above a single edge bay, and...
