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.
