In order to evaluate the performance of ZnO nanowire field emission display under different temperature, the temperature dependence of field emission current of a fully-sealed diode-structured field emission device using ZnO nanowire cold cathode was studied when the temperature changed from −60°C to 80°C. The pressure inside the device was also measured. It is found that the emission current decreases...
The vacuum level inside a FED device significantly influences the performance of the field emitters. In order to investigate the pressure inside a fully-sealed FED, and in particular to monitor the pressure in situ during the aging process, an ion gauge was integrated to the device. The pressure inside the device was measured during the sealing process and after activation of getters. The pressure...
