Graphene on silicon: effects of the silicon surface orientation on the work function and carrier density of graphene
Y. W. Sun, D. Holec, D. Gehringer +4
Density functional theory has been employed to study graphene on the (111), (100) and (110) surfaces of silicon (Si) substrates. There are several interesting findings. First, carb…
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…
Machine Learning Predicts Laboratory Earthquakes
Bertrand Rouet-Leduc, Claudia Hulbert, Nicholas Lubbers +3
Forecasting fault failure is a fundamental but elusive goal in earthquake science. Here we show that by listening to the acoustic signal emitted by a laboratory fault, machine lear…
A study of the optical and polarisation properties of InGaN/GaN multiple quantum wells grown on a-plane and m-plane GaN substrates
D. Kundys, D. Sutherland, M. Davies +8
In this paper we report on a comparative study of the low temperature emission and polarisation properties of InGaN/GaN quantum wells (QWs) grown on nonpolar a-plane and m-plane fr…
