マテリアルサイエンス系セミナー Electronic structure of worm-eaten graphene Professor Kyozaburo Takeda Graduate School of Advanced Science and Engineering, Waseda University 日 時：平成２８年９月１２日（月） １４：００ ～ １５：３０ 場 所：マテリアルサイエンス系研究棟Ⅳ棟８階 中セミナー室 講演要旨： We theoretically study the electronic structure of graphenes having several kinds of imperfections such as atomic vacancies and heteroatom replacement. We consider twelve different configurations of vacancies and thirty-nine different geometries of heteroatom replacements in order to take into account the random conformations of imperfections approximately. To systematically give a perspective understanding of the defect and states caused by the atomistic voids and/or vacancies and by the heteroatom replacements, we have carried out the tight-binding (TB) calculation. We study the orbital hybridization to clarify the origin and formation of and defect states arising from the imperfections. We further discuss the electronic structure around the Fermi level through the TB band calculation. 講演者略歴： 1983 1983 - 1995 1995 - 1997 1997 - present Doctor of Engineering, Keio University NTT Basic Research Laboratory Associate Professor, Waseda University Professor, Waseda University 参加申込・予約は不要です。直接会場にお越しください。 お問い合わせ先：共通事務管理課 共通事務第三係 （E-mail：ms-secr）
