Electron-vacancy scattering in SrNbO and SrTiO: A DFT-NEGF study
Victor Rosendal, Nini Pryds, Dirch Hjorth Petersen +1
Oxygen vacancies are often attributed to changes in the electronic transport for perovskite oxide materials (ABO). Here, we use density functional theory (DFT) coupled with non…
Provoking topology by octahedral tilting in strained SrNbO
Alla Chikina, Victor Rosendal, Hang Li +17
Transition metal oxides with a wide variety of electronic and magnetic properties offer an extraordinary possibility to be a platform for developing future electronics based on unc…
Octahedral distortions in SrNbO: Unraveling the structure-property relation
Victor Rosendal, Walber Hugo Brito, Milan Radovic +4
Strontium niobate has triggered a lot of interest as a transparent conductor and as a possible realization of a correlated Dirac semi-metal. Using the lattice parameters as a tunab…
Bubbles in graphene - a computational study
Mikkel Settnes, Stephen R. Power, Jun Lin +2
Strain-induced deformations in graphene are predicted to give rise to large pseudomagnetic fields. We examine theoretically the case of gas-inflated bubbles to determine whether si…
Patched Green's function techniques for two dimensional systems: Electronic behaviour of bubbles and perforations in graphene
Mikkel Settnes, Stephen R. Power, Jun Lin +2
We present a numerically efficient technique to evaluate the Green's function for extended two dimensional systems without relying on periodic boundary conditions. Different region…
Dual-probe spectroscopic fingerprints of defects in graphene
Mikkel Settnes, Stephen R. Power, Dirch H. Petersen +1
Recent advances in experimental techniques emphasize the usefulness of multiple scanning probe techniques when analyzing nanoscale samples. Here, we analyze theoretically dual-prob…
Theoretical analysis of a dual-probe scanning tunneling microscope setup on graphene
Mikkel Settnes, Stephen R. Power, Dirch H. Petersen +1
Experimental advances allow for the inclusion of multiple probes to measure the transport properties of a sample surface. We develop a theory of dual-probe scanning tunnelling micr…
