Fig. 6From: Reliable Diameter Control of Carbon Nanotube Nanobundles Using Withdrawal VelocityScanning electron microscopy (SEM) images of CNT nanobundles with different diameters due to various withdrawal velocities. a v w = 1 μm/s. b v w = 2 μm/s. c v w = 5 μm/s. d v w = 10 μm/s. All were fabricated under 5V pp and 1 MHz AC electric field. (Scale bar: 3 μm). (Mean ± standard error, n = 5)Back to article page
