Abstract
Large-area patterned boron carbide nanowires (B4C NWs) have been synthesized using chemical vapor deposition (CVD). The average diameter of B4C NWs is about 50 nm, with a mean length of 20 μm. The B4C NWs have a single-crystal structure and conductivities around 5. 1 × 10-2 Ω-1·cm-1. Field emission measurements of patterned B4C NWs films show that their turn-on electric field is 2. 7 V/μm, lower than that of continuous B4C NWs films. A single nanowire also exhibits excellent flexibility under high-strain bending cycles without deformation or failure. All together, this suggests that B4C NWs are a promising candidate for flexible cold cathode materials.
