FIG. 1.

(a) High resolution transmission electron microscopy (HRTEM) image show that Fe was present on either the bottom or top of the individual SWNT bridges. For measuring HRTEM, we carefully prepared a separate specimen on the conductive TEM grid. The scale bar represents . (b) Energy dispersive x-ray analysis spectrum showing the existence of Fe at the junction between the SWNT bridge and one side of the electrode interface of Fig. 1(a) . (c) A schematic drawing of the SWNT junction made in this work. Notice that one side of the junction contains catalyst Fe particles due to the root-growth mechanism of our SWNT.

(a) Temperature dependent current vs drain-source voltage characteristics under a vacuum, (b) Coulomb blockade behavior in the negative regime measured at , and (c) the -type field effect transistor response in the positive regime was maintained at .

FIG. 3.

(a) Channel current vs gate voltage response curves. The inset figure shows the SEM image of the SWNT bridge suspended between the source and drain electrode. (b) Hysteretic curves at low , obtained by sweeping from negative to positive and then in the reverse direction as a function of temperature.

Image of FIG. 4.
FIG. 4.

(a) Channel current vs gate voltage response curves with variation of external magnetic field. (b) Applied magnetic field dependent current behavior at low , showing clear gate voltage dependent magneto-current behavior.
