(color online) Magnetoresistance properties of a single Bi₂Se₃ nanodevice. (a) SEM image of the Bi₂Se₃ nanodevice. The magnified SEM image and the AFM height diagram of the nanodevice are shown in the insets. (b) Temperature-dependent resistance curve at zero magnetic field. (c) Magnetoresistance curve in the vertical magnetic field at 2 K. (d) Magnetoresistance curve in the parallel magnetic field at 2 K. The magnetic field positions of resistance oscillation minima versus oscillation index at 2 K and the FFT of the dR/dB in −9 T to 9 T range are shown in the insets.
