Enhanced field emission characteristics of nitrogen-doped carbon nanotube films grown by microwave plasma enhanced chemical vapor deposition process

Growth of Y-junction bamboo-shaped CNx nanotubes on GaAs substrate using single feedstock

“…The field emission property of CN x nanotubes was observed by several groups [20,37], and it is difficult to compare our field emission result with those reported earlier because of the different morphology, structure, dopant concentration of as-grown CN x nanotubes and different field emission set-up. For CN x nanotubes, Srivastava et al [37] observed the turn on (corresponding to the current density of 10 mA/cm 2 ) and threshold fields (corresponding to the current density of 1 mA/cm 2 ) of 1.95 and 3.55 V/mm, respectively.…”

Wang et al [20] showed the field emission performance of well-aligned CN x nanotubes, and the current density of 80 mA/cm 2 was observed at an applied field of 2.6 V/mm.…”

Electron field emission properties of conducting polymer coated multi walled carbon nanotubes

“…The presence of graphitic layer between the emitter and the carbon woven provides better adhesion. However, further studies are required to bring out the exact dynamics behind the emission process [27].…”

Microwave plasma CVD-grown graphene–CNT hybrids for enhanced electron field emission applications

“…As a result, the CNT growing on such clusters is expected to be influenced by these defects. Hence, during the growth process, as a result, defects are expected to propagate and also form in the CNTs [29]. The nature of these defects and their distribution is a subject of debate.…”
