Image of FIG. 1.
FIG. 1.

(a) Optical microscope image of a ribbon crossed with a P3HT nanofiber. The inset is a schematic of the external electrical connections. (b) Optical microscope image of a ribbon crossed with a P3HT cast film. The ribbon width was and the silver contacts are made directly to the active materials.

FIG. 2.

Current-voltage characteristics for the device shown in Fig. 1(a) measured in air (●-filled symbols) and in vacuum (○-empty symbols) when a positive bias was applied to the P3HT arm with the negative bias on the arm and when the bias terminals were reversed (◻). The inset above shows the characteristic curves for a device fabricated from a ribbon crossed with a P3HT cast film shown in Fig. 1(b). The inset below shows the energy band diagram for the diode.

Image of FIG. 3.
FIG. 3.

(a) Drain source current vs drain source voltage curves for a single electrospun ribbon (open symbols-first quadrant axes) when placed in a FET configuration for different gate bias voltages (−5, 0, and 5 V). (b) Drain source current vs drain source voltage curves for a single electrospun P3HT nanofiber (filled symbols-third quadrant axes) when placed in a FET configuration for different gate bias voltages (−5, 0, and 5 V).

Image of FIG. 4.
FIG. 4.

Expanded plot at low bias voltage of the curve shown in Fig. 2. Inset: semilog plot of the forward bias current as a function of forward bias voltage.

Image of FIG. 5.
FIG. 5.

Current-voltage characteristic curves for the diode when used as a UV light sensor: (◻) in the absence of UV, (○) in the presence of (UV), and (△) after the UV light source was switched off. Inset: characteristic curves for the device fabricated from a ribbon crossed with a P3HT drop cast film: (◻) in the absence of UV and (○) in the presence of UV.
