Observation of electron weak localization and correlation effects in disordered graphene被引量:1
《Science China(Physics,Mechanics & Astronomy)》2009年第9期1293-1298,共6页TAN ChangLing TAN ZhenBing MA Li QU FanMing YANG Fan CHEN Jun LIU GuangTong YANG HaiFang YANG ChangLi LU Li 
Supported by the National Natural Science Foundation of China (Grant Nos. 10774172 and 10874220);the National Basic Research Program of China from the MOST (Grant No. 2006CB921304)
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...
