Figure 1: Magnetotransport of a nanowire with diameter ∼115 nm (Device 1).

(a) High-resolution transmission electron microscopy image of a typical nanowire indicates <112> growth direction with interplanar space ∼0.73 nm. Scale bar, 5 nm. (b) Schematic diagram of the four-terminal device with applied magnetic field aligned with the length. (c) Resistance as a function of magnetic field at different temperatures from 1.5 to 20 K. (d) The oscillations in conductance as a function of magnetic field after subtracting background. (e) FFT spectrums of the conductance oscillations. (f) Plot of the temperature dependence of the FFT peak amplitude. The dashed line indicates the fitting by the T⁻¹ dependence.
