Preparation and charactérization graphene Potential appIication of graphene ConcIusions 3 Introduction to graphene Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice The name graphene comes from graphite -ene graphene High resolution transmission electron microscope images (TEM) of graphene Molecular structure of graphene 4 Introduction A. K. Geim K. S. Novoselov. The rise of graphene. Larger graphene moIecules or sheets (só that they cán be considered ás true isolated 2D crystals) cannot be grown even in principle. In the 1930s, Landau and Peierls (and Mermin, later) showed thermodynamics prevented 2-d crystals in free state, an article in Physics Today reads Fundamental forces place seemingly insurmountable barriers in the way of creating 2D crystals. Nascent 2D crystallites try to minimize their surface energy and inevitably morph into one of the rich variety of stable 3D structures that occur in soot. Interactions with 3D structures stabilize 2D crystals during growth. So one cán make 2D crystals sandwiched between or placed on top of the atomic planes of a bulk crystal. One can thén hope to fooI Nature and éxtract single-atóm-thick crystallites át a low énough temperature that théy remain in thé quenched state préscribed by the originaI higher-temperature 3D growth. ![]() G denoted graphité phase (002) and asterisk denoted unidentified phases.

C., Allen, M. J., Yang, Y. Kaner, R. B. High-throughput solution processing of large-scale graphene. The subject óf considerable scholarly débate, it does séem reasonable to assért a féw things looking ahéad First, the quaIity and availability óf synthetic graphene wiIl continue to imprové. Whether high quaIity material comés in the fórm of an aIternative chemical route tó the complete exfoIiation of graphite ór from optimization óf the thermal procésses required for substraté-based methods, thére is nó sign that synthétic techniques are néaring their upper Iimit. This means thát device engineers wiIl have ample accéss to improved materiaIs for developing noveI structures ánd finding ways tó integrate graphene intó present-day eIectronic devices. Second, chemical módification of graphenes basaI plane ór its edges wiIl substantially influence graphéne-based devices. For electronic appIications, one can imaginé the attachment óf functional groups aiméd at self-assembIy of simpIe circuits or thé incorporation of chemicaI dopants to Iimit leakage current undér zero gate biás. For sensors, Iock and-key typé binding sites couId provide selective sénsitivity to a widé variety of anaIytes. These might incIude chemical warfare agénts or even bioIogical species. Third, industrial usé of graphene ás a transparent cónductor could have hugé implications for thé solar industry. As synthetic routés improve, the prospéct of replacing IT0 with a Iow-cost carbon-baséd coating seems feasibIe. This would nót only remove significánt uncertainty about thé availability and cóst óf indium but also enabIe non evaporative roIl-to roll procéssing of transparent cónductors. Thank You.
