1Observation of electron weak localization and correlation effects in disordered graphene显示文摘We have studied the electron transport properties of a disordered graphene sample, where the disorder was intentionally strengthened by Ga+ ion irradiation. The magneto-conductance of the sample exhibits a typical two-dimensional electron weak localization behavior, with electron-electron interaction as the dominant dephasing mechanism. The absence of electron anti-weak localization in the sample implies strong intersublattice and/or intervalley scattering caused by the disorders. The temperature and bias-voltage dependencies of conductance clearly reveal the suppression of conductance at low energies, indicating opening of a Coulomb gap due to electron-electron interaction in the disordered graphene sample.TAN ChangLing TAN ZhenBing MA Li QU FanMing YANG Fan CHEN Jun LIU GuangTong YANG HaiFang YANG ChangLi LU Li 2009Science China(Physics,Mechanics & Astronomy)2009,52,9:1
