Stability Range for a Flat Graphene Sheet Subjected to In Plane Deformation
571 Graphene is a flat monatomic carbon layer where each atom has covalent bonds with its three neighbors (see Fig. 1a). Due to its unique mechanical, physical, and optical characteristics, graphene is promising for different technological applications. In recent years, the effects of significant elastic strains on the mechan ical and physical properties of graphene and other low dimensional ca...
متن کاملDeformation and Failure of Graphene Sheet and Graphene-Polymer Interface
With a monolayer honeycomb-lattice of sp-hybridized carbon atoms, graphene has demonstrated exceptional electrical, mechanical and thermal properties. One of its promising applications is to create graphene-polymer nanocomposites with tailored mechanical and physical properties. In general, the mechanical properties of graphene nanofiller as well as graphene-polymer interface govern the overall...
متن کاملScattering of graphene plasmons by defects in the graphene sheet.
A theoretical study is presented on the scattering of graphene surface plasmons (GSPs) by defects in the graphene sheet they propagate in. These defects can be either natural (as domain boundaries, ripples, and cracks, among others) or induced by an external gate. The scattering is shown to be governed by an integral equation, derived from a plane wave expansion of the fields, which in general ...
متن کاملSIMULATION OF TETRACYCLINE ONTO GRAPHENE NANO SHEET
Tetracycline (TC) is a broad spectrum of antibiotic which is used to cure infectious diseases and cancer. It can cause harmful side effects due to its high absorption in all organs. On the other hand graphene is appropriate to carry drug and release it to special target, organ or cell. It may decrease the side effects of the drug dramatically by using low dosage of medicine. Graphene oxide (GO)...
متن کاملFerromagnetism in semihydrogenated graphene sheet.
Single layer of graphite (graphene) was predicted and later experimentally confirmed to undergo metal-semiconductor transition when fully hydrogenated (graphane). Using density functional theory we show that when half of the hydrogen in this graphane sheet is removed, the resulting semihydrogenated graphene (which we refer to as graphone) becomes a ferromagnetic semiconductor with a small indir...
