چکیده
|
In this study the effect of hydrogen ambient environment on the growth of carbon nanotubes by arc discharge plasma in presence of external magnetic field is investigated. the samples collected from cathode deposit are analyzed by field emission scanning electron microscopy and raman spectroscopy. results show an increase in carbon nanotube growth with increase in hydrogen ambient pressure. the magnetic field considerably enhances the growth of carbon nanotube as observed in fesem micrographs. in raman spectrum,high intensity of g peak as compared to d peak indicates the presence of high quality nanotubes. magnetic effect remarkably decreases id/ig ratio from 1.55 to 0.31 for ambient pressure 10 mbar. © 2016 penerbit utm press. all rights reserved.
