LOW-FIELD MAGNETOTRANSPORT STUDY OF LOCALIZATION IN A MESOSCOPIC ANTIDOT ARRAY

LOW-FIELD MAGNETOTRANSPORT STUDY OF LOCALIZATION IN A MESOSCOPIC ANTIDOT ARRAY

Low-field negative magnetoresistance has been studied on Ga+ ion focused-ion-beam-patterned GaAs/Ga1-xAlxAs heterojunctions as a function of carrier density and temperature. The negative magnetoresistance (NMR) is very large at low densities and decreases with increasing carrier density, giving a ma...
