Laboratory/research office Plasma Engineering Laboratory
Non-equilibrium discharge plasma, in which electron temperature easily exceeds several tens of thousands degrees, occurs in many phenomena, for example, natural lightning and discharge lamps. In plasma phase, matter is in a highly excited state and/or highly reactive condition, and so can induce active chemical reactions and/or intense light emission. We are working to create plasma application technologies through our studies of (a) production and control of discharge plasma in an atmospheric environment, in water and in reactive gases; and (b) analysis of fabricated thin films and reactive chemical species.
