Figure 1

(a) The atomic structure of a (10, 10) armchair SWCNT (~1.4 nm in diameter). (b) SEM of SWCNTs on silicon oxide surface. The gold markers are fabricated after SWCNT growth and are used to locate the CNT. (c) Optical image of a fabricated device after EBL step. Gold alignment markers and reservoirs are clearly seen. The white dashed square labeled the barrier area. (d) SEM of the barrier area (~2 μm in width). One SWCNT passes the barrier and bridges two reservoirs. The SWCNT in the reservoirs will disappear after oxygen plasma.
