The device characteristics of the carbon nanotube (CNT) vacuum field emission (VFE) differential amplifier (diff-amp) is improved. The circuit-level characterization of the device was performed. SEM was used study the rectangular and circular arrays of the CNT triode array on the single chip VFE diff-amp
The effect of thermal annealing on the field emission properties of double-walled carbon nanotubes (DWCNT) grown by chemical vapour deposition is studied. The properties of the DWCNTs were examined using SEM, TEM, Raman and TGA analysis. It was found that high-temperature annealing enhances the field emission performance of DWCNTs
A lateral carbon nanotube (CNT) field emission device with a metallic anode is fabricated through a dual-mask microfabrication process complemented with a two-step microwave plasma-enhanced chemical vapor deposition. SEM was employed to characterize the structure of the fabricated device
