| 释义 | graphene noun[ U ] uk /ˈɡræf.iːn/ us /ˈɡræf.iːn/ chemistry specialized a form of carbon consisting of sheets that have the thickness of one atom. The atoms are arranged in a honeycomb pattern (= a pattern of shapes with six sides).石墨烯 Physics: atoms, molecules & sub-atomic particles acceptor alpha particle anti-radical antilepton antimatter antineutrino beta decay beta particle Higgs boson interatomic interelectronic interionic intermolecular monatomic multi-molecular multiparticle muon neutrino positron relative atomic mass You can also find related words, phrases, and synonyms in the topics: Chemical elements Examples of graphenegraphene It was found that hydrogen does not destroy the graphene at these energies, but is instead absorbed or reflected by the graphene. After repeated bouncing between graphene layers, the incident atom is trapped. It is seen that the interstitial does not diffuse across the graphene layer. Incidence at the lowest energies is shown to distort the graphene structure. The hydrogen adsorption rate is found to be dependent on the incident hydrogen energy and not on graphene temperature. The rate of hydrogen adsorption was shown to be dependent on the incident energy and not on the graphene temperature. The carbon wall is treated as graphene layers which are a minimal structure of both a graphite and a carbon fiber. In both cases curved graphene sheets can be observed together with onion-like particles and defective structures which we have defined fullerene-like structures. The incident atom gradually loses kinetic energy by repulsion of the carbon atom as it penetrates several graphene layers. The kinetic energy converted from potential energy is diffused into the entire atoms in the graphene through the overhanging carbon atom. Such interactions are typical in chemical sputtering experiments, and knowledge of the fundamental behavior of hydrogen and graphene in collisional conditions is essential for modeling the sputtering mechanism. In the present study, this mechanism is examined in detail through simulation of the collision of hydrogen atoms with graphene as one of the fundamental processes in plasma-carbon interaction. Old papers were unearthed in which researchers tried to isolate graphene starting with intercalated compounds.
