Cold cathodes of carbon nanotubes (CNTs) were deposited on the glass substrate by the electrophoretic deposition (EPD) method. The cathodes were tested in the diode construction with the cathode–anode gap of 170 μm in vacuum. The emission characteristics of the CNTs film cathodes have as good properties as those by screen printing and better emission uniformity. The influence of the voltage between...
The carbon nanotubes (CNTs) were synthesized by low pressure chemical vapor deposition (CVD) in the temperature range of 500–750°C. The dependence of field emission properties of screen-printed cathode on the CNTs growth temperatures was studied. The scanning electron microscope (SEM) images and Raman spectra showed that with the temperature increasing from 500°C to 750°C, the average diameter of...
