High Current Emission from Patterned Aligned Carbon Nanotubes Fabricated by Plasma-Enhanced Chemical Vapor Deposition
Vertically, carbon nanotube (CNT) arrays were successfully fabricated on hexagon patterned Si substrates through radio frequency plasma-enhanced chemical vapor deposition using gas mixtures of acetylene (C2H2) and hydrogen (H2) with Fe/Al2O3 catalysts. The CNTs were found to be graphitized with multi-walled structures. Different H2/C2H2 gas flow rate ratio was used to investigate the effect on ...
متن کاملDetermination of Optical Properties in Germanium Carbon Coatings Deposited by Plasma Enhanced Chemical Vapor Deposition
In this research, Germanium-carbon coatings were deposited on ZnS substrates by plasma enhanced chemical vapor deposition (PECVD) using GeH4 and CH4 precursors. Optical parameters of the Ge1-xCx coating such as refractive index, Absorption coefficient, extinction coefficient and band gap were measured by the Swanepoel method based on the transmittance spectrum. The results showed that the refra...
متن کاملBright infrared emission from electrically induced excitons in carbon nanotubes.
We used the high local electric fields at the junction between the suspended and supported parts of a single carbon nanotube molecule to produce unusually bright infrared emission under unipolar operation. Carriers were accelerated by band-bending at the suspension interface, and they created excitons that radiatively recombined. This excitation mechanism is approximately 1000 times more effici...
متن کاملStudy on structures and electron field emission of nitrogenated carbon nanotips grown by plasma-enhanced hot filament chemical vapor deposition
Nitrogenated carbon nanotips (NCNTPs) with different structures were synthesized by plasmaenhanced hot filament chemical vapor deposition under different time using methane, nitrogen and hydrogen as the reaction gases. The results of field emission scanning electron microscopy, microRaman spectroscopy and X-ray photoelectron spectroscopy indicate that the NCNTPs are amorphous structure and they...
متن کاملSurface structure and field emission property of carbon nanotubes grown by radio-frequency plasma-enhanced chemical vapor deposition
In this study, large-area and low-temperature synthesis of carbon nanotubes on glass substrates with transformer coupled plasma (TCP) type radio-frequency plasma-enhanced chemical vapor deposition (rf PE-CVD) system was performed, and their surface structures and field emission property were analyzed. By varying process conditions such as Ni layer thickness, gas flow rate, NH3 etching time, pla...
