FIG. 1.

(a) Low-magnification image and (b) electron diffraction pattern of a whisker prepared by heating of a whisker. (c) Low-magnification image and (d) electron diffraction pattern of the whisker after structural change due to the impressive current. (e) High-resolution image of the surface of the whisker in (c). The whisker is composed of multilayered carbon hollow capsules of less than ten nanometers in diameter. The whisker in (c) is the filament emitting visible light.

FIG. 2.

Current-voltage curve of the whisker in Fig. 1(c). The abrupt increase of current at the bias voltage of indicates that the structural change occurs. Cross indicates the fracture of the contact.

FIG. 4.

Emission intensity of a whisker composed of carbon capsules as a function of the electric power.
