Abstract

We present fabrication of the carbon nanotubes (CNTs) electron guns for the cathode ray tubes (CRT) and their electron emission properties as well as light emitting characteristics. The CNTs were grown on Si substrate and CRT cathode cap by low-pressure chemical vapor deposition. The CNTs consisted of multi-wall nanotubes (MWNTs) with an outer diameter range from 20 to 30nm. The MWNTs emitter turns on at 2.2V/μm and starts emitting 1mA/cm² at 2.9V/μm on the diode device. For practical display application, the fabricated CNTs electron gun was inserted into 19in-sized CRT. We have investigated their long-term emission stability for 1000h and demonstrated the window raster.
