CrAs Monolayer: Low Buckled 2D Half‐Metal Ferromagnet

Buckled circular monolayer graphene: a graphene nano-bowl.

We investigate the stability of circular monolayer graphene subjected to a radial load using non-equilibrium molecular dynamics simulations. When monolayer graphene is radially stressed, after some small circular strain (∼0.4%) it buckles and bends into a new bowl-like shape. Young's modulus is calculated from the linear relation between stress and strain before the buckling threshold, which is...

Anomalous Hall effect in 2D Rashba ferromagnet

Anomalous Hall Effect in a 2D Rashba Ferromagnet.

Skew scattering on rare impurity configurations is shown to dominate the anomalous Hall effect in a 2D Rashba ferromagnet. The mechanism originates in scattering on rare impurity pairs separated by distances of the order of the Fermi wavelength. The corresponding theoretical description goes beyond the conventional noncrossing approximation. The mechanism provides the only contribution to the a...

Electronic properties of a pristine and NH3/NO2 adsorbed buckled arsenene monolayer

Analogous to exfoliated 2D sheets of black phosphorene, arsenene is an atomically thin layer of the arsenic crystal. In this paper, we investigate the sensitivity of a pristine arsenene sheet for NH3 and NO2molecules in terms of binding energy, nature of bonding, density of states and current–voltage characteristics. The calculated results based on density functional theory find that both NH3 a...

Source code based protection against CRAs

As the threat potential of Code-Reuse Attacks (CRAs) is rising we want to develop a tool that can mitigate such state-of-the-art attacks (e.g., the attack dubbed Counterfeit Object-Oriented Programming (COOP)). This attack is particularly hard to defend against since traditional Control Flow Integrity (CFI) approaches are useless. Based on source code recompilation techniques we want to harden ...
