Research Interests and achievement |

Updated on September 3, 2006
My research interest is to study the physics and application of the plasma. Plasma
consists of electrons, ions and neutral particles. It will demonstrate collective
behaviors, such as wave motions, when the density of charged particles is high
enough. Above all, the interactions inside plasmas are mostly ¡¨ heterogeneous¡¨,
which means they involve interactions among violet light, electrons, ions, radicals,
especially energetic particles. Consequently, there are many novel physical and
chemical reactions occurring in plasmas. For instance, the growth of diamond
films, carbon nanotubes. My research topics includes: (1) microwave large area
surface wave plasma source and plasma resonance; (2) plasma immersion ion implantation
and the dynamics of sheath; (3) inductively coupled plasma sources and plasma
heating modes; (4) low temperature atmospheric plasma sources (dielectric barrier
discharges, plasma jets); (5) diamond /DLC films, field emission; (6) single
crystal diamond rod and devices; (7) liquid crystal alignment by plasma beams.
