Characteristics of the fabricated NFs. (a) Results of the fast oscillation (at ~32 kHz frequency) experiment. (i) The time delay Δt of the shear stress τ (blue and red curves) with respect to the strain γ (black curve) for the NF. (ii) The hysteretic responses between the shear stress and strain for a different oscillation amplitude a. (b) Electrical properties of the NF. (i) Electrical current is in situ measured by connecting the fabricated NF with two electrodes after fabrication. The current through the NF shown in (ii) Measured current signal with various current spikes which may be associated with rearrangement of the constituent nanoparticle clusters within the NF by electric field. (c) Optical properties of the NF. (i) The XRD results exhibits the spectral peak associated with the Au (111) particles. (ii) Halogen lamp illumination shows the well and uniformly distributed Au nanoparticles within the NF, as indicated by the gold color.
