(Color) (a) Schematic cross section of SWNT junction diode. The split gates VG1 and 2 are used to electrostatically dope a SWNT. For example, a junction with respect to the contact can be formed by biasing and ; (b) SEM of a SWNT over a split gate.
Device transfer characteristics with , and .
(Color) characteristics of a single SWNT when electrostatically doped to form a junction (), junction , or FET .
(Color) curve plotted in absolute magnitude of the current. The band diagram illustrates the band structures during forward and reverse bias near the vicinity of the junction. The fit is to the diode equation given with an ideality factor of and .
