From: Highly flexible and robust N-doped SiC nanoneedle field emitters
(a) Digital photographs showing the high flexibility of SiC nanoneedles grown on carbon fabric with various bended states (suspended; folded; bended with a radius of ~1.2 cm; bended with a radius of ~0.3 cm). (b) J–E curves and (c) F–N plots of sample S3-1 after 0, 50, 100, 150 and 200 bending cycles. (d–f) Schematic illustrations of sample S3-1 in concave, flat and convex states, respectively. (g) J–E curves of sample S3-1 in concave, flat and convex states. (h) Field emission stability of sample S3-1 in concave, flat and convex states.
