investigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولLocalized states at zigzag edges of multilayer graphene and graphite steps
We report the existence of zero energy surface states localized at zigzag edges of Nlayer graphene. Working within the tight-binding approximation, and using the simplest nearestneighbor model, we derive the analytic solution for the wavefunctions of these peculiar surface states. It is shown that zero energy edge states in multilayer graphene can be divided into three families: (i) states livi...
متن کاملGiant edge state splitting at atomically precise graphene zigzag edges
Zigzag edges of graphene nanostructures host localized electronic states that are predicted to be spin-polarized. However, these edge states are highly susceptible to edge roughness and interaction with a supporting substrate, complicating the study of their intrinsic electronic and magnetic structure. Here, we focus on atomically precise graphene nanoribbons whose two short zigzag edges host e...
متن کاملUniversal Density of States for Carbon Nanotubes
The density of states in the vicinity of the Fermi level of single-wall carbon nanotubes can be expressed in terms of a universal relationship that depends only on whether the nanotube is metallic or semiconducting. We compare the predictions of this approximate relationship with densities of states calculated using first-principles band structure results. These comparisons show that this appro...
متن کاملLong-wavelength local density of states oscillations near graphene step edges.
Using scanning tunneling microscopy and spectroscopy, we have studied the local density of states (LDOS) of graphene over step edges in boron nitride. Long-wavelength oscillations in the LDOS are observed with maxima parallel to the step edge. Their wavelength and amplitude are controlled by the energy of the quasiparticles allowing a direct probe of the graphene dispersion relation. We also ob...
