Phonon and structural changes in deformed Bernal stacked bilayer graphene.
NANO LETTERS, no. 2 (2012): 687-693
We present the first Raman spectroscopic study of Bernal bilayer graphene flakes under uniaxial tension. Apart from a purely mechanical behavior in flake regions where both layers are strained evenly, certain effects stem from inhomogeneous stress distribution across the layers. These phenomena such as the removal of inversion symmetry in...更多
