Raman spectroscopy study of nano sheets of graphene and measurement of their resistivity
Graphene is a promising candidate for future high-speed electronics applications. It is a thin layer of pure carbon in which every atom is available for chemical reaction from two sides (due to the 2D structure). This is the only form of carbon (or solid material) with this characteristic feature. Graphene oxide (GO) was synthesized through the oxidation of graphite using the Hummer’s method, i...
متن کاملEmission properties of Ga2O3 nano-flakes: effect of excitation density
In the quest of developing high performance electronic and optical devices and more cost effective fabrication processes of monoclinic β-Ga2O3, new growth techniques and fundamental electronic and optical properties of defects have to be explored. By heating of dissolved metallic Ga in HCl in a NH3 and N2 atmosphere, nano-flake films of monoclinic β-phase Ga2O3 were grown as confirmed by XRD. F...
متن کاملinvestigation 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 اولEffect of oxygen plasma etching on graphene studied using Raman spectroscopy and electronic transport measurements
In this paper, we report a study of graphene and graphene field effect devices after their exposure to a series of short pulses of oxygen plasma. Our data from Raman spectroscopy, back-gated field-effect and magnetotransport measurements are presented. The intensity ratio between Raman ‘D’ and ‘G’ peaks, ID/IG (commonly used to characterize disorder in graphene), is observed to initially increa...
متن کاملRaman spectroscopy of graphene edges.
Graphene edges are of particular interest since their orientation determines the electronic properties. Here we present a detailed Raman investigation of graphene flakes with edges oriented at different crystallographic directions. We also develop a real space theory for Raman scattering to analyze the general case of disordered edges. The position, width, and intensity of G and D peaks are stu...
