Disruption of the $s p^{2}$ bonding by the compression of the $π$ -electronic orbitals of graphene at various stacking orders

Yiwei Sun, David Holec, Dominik Nöger +2

We investigate the behaviour of the $π$ -electrons under compression and the effect of the stacking order of graphene layers. First we find that electrons can hardly be squeezed thr…

3D strain in 2D materials: Experimental test in unsupported monolayer graphene under pressure

Y. W. Sun, W. Liu, I. Hernandez +4

Previous Raman measurements on supported graphene under high pressure reported a very different shift rate of in-plane phonon frequency of graphene (16 cm $^{- 1}$ GPa $^{- 1}$ ) from gr…

Analysis of the inverse square-root size effect in the plasticity of metals

T. T. Zhu, B. Ehrler, X. D. Hou +2

Small-scale mechanical behaviour shows significant departures from classical elastic-plastic theory. In a remarkable number of instances, the strength of a material appears to scal…
