Disruption of the bonding by the compression of the -electronic orbitals of graphene at various stacking orders
Yiwei Sun, David Holec, Dominik Nöger +2
We investigate the behaviour of the -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 cmGPa) from gr…
The Effect of Humidity on the Interlayer Interaction of Bi-layer Graphene
A. Qadir, Y. W. Sun, W. Liu +4
The lubricating ability of graphite largely depends on the environmental humidity, essentially the amount of water in between its layers. In general, intercalated molecules in laye…
Mapping the potential within a nanoscale undoped GaAs region using a scanning electron microscope
B. Kaestner, C. Rodenburg, C. J. Humphreys
Semiconductor dopant profiling using secondary electron imaging in a scanning electron microscope (SEM) has been developed in recent years. In this paper, we show that the mechanis…
