Application of carbon nanotubes to the cathode ray tube-electron gun

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 30 nm. The MWNTs emitter turns on at 2.2 V/mum and starts emitting 1 mA/cm(2) at 2.9 V/mum on the diode device. For practical display application, the fabricated CNTs electron gun was inserted into 19 in-sized CRT. We have investigated their long-term emission stability for 1000h and demonstrated the window raster. (C) 2002 Elsevier Science Ltd. All rights reserved.
