ABSTRACT=<p>A field emission from a lateral emitter made by a multiwalled carbon nanotube (MWCNT) yarn was investigated. The lateral emitter showed an excellent field emission performance with a low turn-on electric field of 1.13 V/μm at an emission current of 1 μA, high emission current of 0.2 mA at an applied voltage of 700 V, and longtime emission stability for over 20 h without any significant current decay under an initial emission current of about 0.10 mA. The lateral emitter also demonstrated a uniform line emission pattern. It is suggested that the field emission occurs from the outmost MWCNTs that are protruding out from the yarn surface.</p>
