Figure 2From: Electrical transport properties of small diameter single-walled carbon nanotubes aligned on ST-cut quartz substratesSEM images of SWNTs synthesized from different catalyst pads. Size of catalyst pad is 100 × 10 μm in (a), 10 × 2 μm in (b), and 10 × 2 μm in (c) with deposited electrodes. All scale bars are 40 μm.Back to article page
