摘要: Carbon dust particles with radius of a few hundreds nanometers are formed in steady-state plasma produced by an electromagnetic surface wave at 200 MHz very low-pressure conditions. The influence applied magnetic field is evidenced ex situ methods (scanning and transmission electron microscopy, Raman spectroscopy). observed spherical aggregates graphite nanocrystals embedded amorphous carbon shells. In addition, the size increases intensity. Growth occurs as confined near sheath edge their confinement improved applying corresponding electric this region. As consequence, average particle directly related to
