Abstract:
An experimental study of the two-, three-, and four-terminal resistance of a ballistic wire is carried out. The wire is fabricated on the basis of high-mobility 2D electron gas in an AlGaAs/GaAs heterojunction. Different behavior of mesoscopic fluctuations of multiterminal resistances is observed depending on the gate voltage and magnetic field. At $B=0.45$ T, the four-terminal resistance drops almost to zero and features resembling a ballistic conductance quantization are observed.
