Title:The Properties of Nitride on Efficient Field Emission Displays
Alireza Khorami (IRIB Univ., Iran) and Shirin Ghanbari (IRIB Technical Research Center, Iran)
Abstract: Field emission display (FED) is a promising flat display technology and is based on an array of nanotube based emitters. Each pixel has several nanotubes as a cold cathode (emitter) to release electrons through certain voltages between the electrodes. It is when the electrons collide with phosphors that visible light is emitted. Although plasma display panels (PDPs) and LCDs are delivering quality images, their luminous efficiency is still reported to be low . One of the major issues concerning the enhancement of luminance and luminous efficiency are in the investigation of utilizing Nitride element in the cold cathode . Nitride materials such as Gallium nitride (GaN) have attracted much attention due to their superior properties including chemical stability and negative or low positive electron affinity . In this regards, it is desirable to develop a field emitter which operates at a high emission current and a low applied voltage in comparison with Carbon nanotubes (CNTs). However, amongst all types of CNTs, vertically grown carbon nanotubes are known to be promising electron emitters. The vertical alignment of these superior emitters enhances the field effect on the tip of the CNTs, making them ideal for FEDs.?
