Strain Engineering of Graphene’s Electronic Structure

Strain engineering of graphene's electronic structure.

We explore the influence of local strain on the electronic structure of graphene. We show that strain can be easily tailored to generate electron beam collimation, 1D channels, surface states, and confinement. These can be seen as basic elements for all-graphene electronics which, by suitable engineering of local strain profiles, could be integrated on a single graphene sheet. In addition this ...

Magneto-electronic properties of multilayer graphenes.

This article reviews the rich magneto-electronic properties of multilayer graphene systems. Multilayer graphenes are built from graphene sheets attracting one another by van der Waals forces; the magneto-electronic properties are diversified by the number of layers and the stacking configurations. For an N-layer system, Landau levels are divided into N groups, with each identified by a dominant...

An Iridatropylium Cation: Investigation of Electronic Structure

A study of the [C6 H6 Ir(PH3 )3 ]+ iridatropylium cation structure based on frontier orbital analysis, thermodynamic analysis, and natural bond orbital (NBO) theory is the main aim of the present research. Also, HOMO, LUMO energies, hardness, electrophilicity and chemical potential were calculated. Structural analysis indicated the optimized geometry shows a good agreement with the experimental...

Effects of strain on the electronic structure of VO2

We present cluster-dynamic mean field theory DMFT continuous time quantum Monte Carlo method calculations based on a downfolded tight-binding model in order to study the electronic structure of vanadium dioxide VO2 both in the low-temperature M1 and high-temperature rutile phases. Motivated by the recent efforts directed toward tuning the physical properties of VO2 by depositing films on differ...
