Figure 4From: Electrical transport properties of an isolated CdS microrope composed of twisted nanowires Current vs ( V / V t − 1) plots at 80, 70, and 60 K. The straight line is the fitting to equation I ∞ (V/V t − 1) ζ, V t is the threshold voltage. The calculated exponent ζ is 2.32 for 80 K, 2.38 for 70 K, and 2.59 for 60 K.Back to article page
