FIG. 1.

(Color online) (a) SEM image of bended yarn; (b) magnified SEM image of the tips of the yarn; (c) schematic model of the MWCNT yarn, heating electrodes, and phosphor anode; (d) image of yarn heated to incandescence; the dashed lines indicate the position of the electrodes.

FIG. 2.

(Color online) (a) FE curves of MWCNT yarn at different temperatures; (b) FN curves at different temperatures; the curves below are roughly divided into four parts.

FIG. 3.

(Color online) (a) FE current switches between RT and 1332 K; (b) FE anode phosphor images at RT and 1332 K.
