Local Gating in Carbon Nanotubes

Single Wall Carbon Nanotubes (SWNTs) exhibit a host of remarkable physical properties. Their unique electronic structure suggests that SWNTs are ideal for studying the rich physics of one-dimensional (1D) quantum systems. Local gating enables the creation of tunable structures where such phenomena can be experimentally studied. We have fabricated locally-gated SWNT devices and have performed low-temperature electronic transport measurements. We present our recent data and discuss the results in the context of 1D mesoscopic systems.
