Abstract

We report on a novel contact scheme which for the first time makes possible magnetotransport measurements on individual quasi-1D quantum wires prepared by cleaved edge overgrowth. Contacting is achieved via two isolated 2D electron systems that are connected to one another by the quantum wire under study. Two-terminal magnetoresistance measurements along our modulation-doped quantum wires exhibit ...
