Abstract: An efficient carbon nanotubes（CNTs） field emission cathode has been successfully fabricated by combining electrophoresis and by electrochemical deposition technology.In fabrication,the silver patterns are deposited on an indium tin oxide glass by electrochemical method and then the CNTs are covered onto surface of the silver patterns by electrophoretic method.The cathode shows that excellent field emission characteristic,including a turn-on electric field of 2.8V/μm and an emission current density of 1.692mA/cm² at an applied electric field of 5.5V/μm.The excellent field emission characteristic may be attributed to that surface electric field of CNTs are enhanced by edge and hills-like surface of silver pattern.The cathode is a promising candidate for large scale carbon nanotubes–based field emission display,due to its simple fabrication processes and excellent field emission characteristic.
