FIG. 1.

(a) Photograph of an array of diameter VACNT columns. The area of the array is , the vertical sidewalls and sharp edges of top surfaces are noticeable from the SEM micrograph of a VACNT-column array in the inset. (b) A higher magnification SEM image of a sidewall shows that these columns consist of vertically aligned nanotubes.

FIG. 2.

(a) Photograph showing bending of a freestanding PDMS-supported VACNT-column array. The inset is a SEM micrograph showing the PDMS-free top surface of a VACNT column. (b) A photograph of a CNT-column array transferred to a plastic film. Conductive epoxy was used as an adhesive agent between the CNT-column array and plastic film, and to secure electrical contact.

FIG. 5.

curves and corresponding FN plots of a freestanding PDMS-supported VACNT-column array. We repeated field-emission measurements for 50 times, and the data corresponding to the 20th and 50th measurements are shown.
