|Issue Date:||15-Jan-2013||Citation:||Wu, R., Zhou, K., Qian, X., Wei, J., Tao, Y., Sow, C.H., Wang, L., Huang, Y. (2013-01-15). Well-aligned SiC nanoneedle arrays for excellent field emitters. Materials Letters 91 : 220-223. ScholarBank@NUS Repository. https://doi.org/10.1016/j.matlet.2012.09.096||Abstract:||Well-aligned SiC nanowire arrays are successfully synthesized on carbon cloth by a facile chemical vapor deposition without using any templates. Such nanowire arrays acting as cold electron emitters exhibit excellent field emission performance with very low turn-on and threshold voltages of 1.3 V μm-1 and 2.2 V μm-1, respectively, and high field enhancement factor (∼3667). The superior field emission properties are mainly attributed to well aligned and tapered morphology of SiC and the enhanced electrons transport in the nanowires due to the good electric contact with the carbon fabric substrate where they grow. © 2012 Elsevier B.V.
