The boundaries of quantum materials can host a variety exotic effects such as topologically robust edge states or anyonic quasiparticles. Here, we show that fermionic systems graphene admit low energy Dirac description exhibit counterintuitive relativistic at their boundaries. As an example, consider carbon nanotubes and demonstrate bulk spinor have non zero charge density on the boundaries, in...
p { margin-bottom: 0.1in; direction: rtl; line-height: 120%; text-align: right; }a:link { color: rgb(0, 0, 255); } In this paper, the reported experimental data related to electrical transport properties in bulk ZnO, ZnMgO/ZnO and ZnMgO/ZnO/ZnMgO single and double heterostructures were analyzed quantitavely and the most important scattering parameters on controlling electron concentratio...
Electronic properties for bcc Fe and hcp Co in bulk state and also Fe-Co alloy were calculated by quantum calculation based on density functional theory and pseudopotential method. Combination of Wannier function and Berry phase theory was used for calculation of anomalous Hall conductivity in above structures. It was seen that split of band by the spin orbit interaction, lying on the Fermi le...
dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...
We demonstrate that bulk band structure can have a strong influence in scanning tunneling microscopy measurements by resolving electronic interference patterns associated with scattering phenomena of bulk states at a metal surface and reconstructing the bulk band topology. Our data reveal that bulk information can be detected because states at the edge of the surface-projected bulk band have a ...
