Quasiparticle Band Structure Calculation of Monolayer , Bilayer , and Bulk
Quasiparticle self-consistent GW calculations of the band structures and related effective mass parameters are carried out for bulk, monolayer and bilayer MoS2. Including excitonic effects within the Mott-Wannier theory, quantitative agreement is obtained between the A, B excitons, measured by absorption [1], and the calculated exciton gap energies at K. The A-B splitting arises from the valenc...
متن کاملElectronic Band Structure of Bulk and Monolayer V2O5
Vanadium oxide (V2O5) is a material that can be fabricated as a thin film of only a few atomic layers thick during mechanical exfoliation due to the weak interlayer interactions, much like how graphene is created. During this project we looked at the band structure of both the bulk and mono-layered V2O5. We used computer software called ABINIT, which is installed on the high performance compute...
متن کاملShear Band Formation in Bulk Metallic Glasses
In recent times, there has been a growing interest in the machining of amorphous metallic alloys, which are also called bulk metallic glasses (BMGs). These materials differ from common polycrystalline metallic alloys, because their atoms do not assemble on a crystalline lattice, and as a result, they have unique physical, mechanical, and chemical properties. A number of BMGs have been found to ...
متن کاملUnified bulk-boundary correspondence for band insulators
The bulk-boundary correspondence, being a question of intensive research interest over the past decades, provides for one of the most quintessential ideas in the topological classification of matter. However, the bulk-boundary correspondence has never been proven in all generality and has in certain scenarios even been shown to fail to hold, depending on boundary profiles of the terminated syst...
متن کاملBand artifacts due to bulk motion.
Band artifacts due to bulk motion were investigated in images acquired with fast gradient echo sequences. A simple analytical calculation shows that the width of the artifacts has a square-root dependence on the velocity of the imaged object, the time taken to acquire each line of k-space and the field of view in the phase-encoding direction. The theory furthermore predicts that the artifact wi...
