Magnetism of substitutional Co impurities in graphene: Realization of single vacancies
We report ab initio calculations of the structural, electronic, and magnetic properties of a graphene monolayer substitutionally doped with Co Cosub atoms. These calculations are done within density-functional theory using the generalized gradient approximation. We focus in Co because among traditional ferromagnetic elements Fe, Co, and Ni , only Cosub atoms induce spin polarization in graphene...
متن کاملDefect controlled magnetism in FeP/graphene/Ni(111)
Spin switching of organometallic complexes by ferromagnetic surfaces is an important topic in the area of molecular nanospintronics. Moreover, graphene has been shown as a 2D surface for physisorption of molecular magnets and strain engineering on graphene can tune the spin state of an iron porphyrin (FeP) molecule from S = 1 to S = 2. Our ab initio density functional calculations suggest that ...
متن کاملRectification in Graphene Self-Switching Nanodiode Using Side Gates Doping
The electrical properties and rectification behavior of the graphene self-switching diodes by side gates doping with nitrogen and boron atoms were investigated using density functional tight-binding method. The devices gates doping changes the electrical conductivity of the side gates and the semiconductor channel nanoribbons. As a result, the threshold voltage value under the forward bias is s...
متن کاملInvestigating the Effect of Doping Graphene with Silicon in the Adsorption of Alanine by Density Functional Theory
In this investigation, the influence of doping graphene with silicon in the adsorption of alanine amino acid was inspected computationally. For this purpose, the structures of pure graphene, silicon doped graphene, alanine and 10 derived products of the alanine reaction with pure and silicon doped nano-adsorbents were optimized geometrically. Afterwards, the values of adsorption energy, formati...
متن کاملTiO2/Graphene oxide nanocomposite as an ideal NO gas sensor: A density functional theory study
We performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped TiO2/Graphene oxide nanocomposites as the adsorbents for the removal of toxic NO molecules in the environment. We presented the most stable adsorption configurations and examined the interaction of NO molecule with these doped and undoped nanocomposites. It turns out...
