The role of spin-orbit interaction in the ultrafast demagnetization of small iron clusters
Maria Stamenova, Jacopo Simoni, Stefano Sanvito
The ultra-fast demagnetization of small iron clusters initiated by an intense optical excitation is studied with time-dependent spin density functional theory (TDSDFT). In particul…
Charge transfer energies of benzene physisorbed on a graphene sheet from constrained density functional theory
Subhayan Roychoudhury, Carlo Motta, Stefano Sanvito
Constrained density functional theory (CDFT) is used to evaluate the energy level alignment of a benzene molecule as it approaches a graphene sheet. Within CDFT the problem is conv…
Spectral Sensitivity of Graphene/Silicon Heterojunction Photodetectors
Sarah Riazimehr, Andreas Bablich, Daniel Schneider +5
We have studied the optical properties of two-dimensional (2D) Schottky photodiode heterojunctions made of chemical vapor deposited (CVD) graphene on n- and p-type Silicon (Si) sub…
Understanding and optimising the packing density of perylene bisimide layers on CVD-grown graphene
Nina C. Berner, Sinéad Winters, Claudia Backes +7
The non-covalent functionalisation of graphene is an attractive strategy to alter the surface chemistry of graphene without damaging its superior electrical and mechanical properti…
Liquid exfoliation of solvent-stabilised black phosphorus: applications beyond electronics
Damien Hanlon, Claudia Backes, Evie Doherty +20
Few layer black phosphorus is a new two-dimensional material which is of great interest for applications, mainly in electronics. However, its lack of stability severely limits our…
