Microplasma device with graphene cathode



  1. Department of Physics, Faculty of Science, Gazi University, 06500 Teknikokullar, Ankara, Turkey


Graphene is used as a cathode material in a microplasma device. Graphene is suitable for plasma systems in terms of excellent conductivity, spatial charge density, and distribution of electrons moving between the anode and cathode. The progressive development of semiconductor technology is based on small chips containing a cathode-anode couple, along with the development of micro and nanoparticles. Graphene is used as a cathode material instead of semiconductor material for the first time to our knowledge. As a new and developing trend, the modeling of plasma systems, cell designs and ideal operating conditions are still being researched theoretically and practically. Plasma treatment of the materials has an important place in technology with increasing plasma studies in recent years. Plasma processing of fascinating materials such as graphene is critical in the aerospace, optical and paper industries, automotive, steel, and biomedical. Graphene has excellent conductivity, and caused high electron density in the plasma system according to our simulation results. Furthermore, an environmentally friendly microplasma device can be achieved with graphene cathode and thus can enhance the efficiency of the plasma system under stable and reliable conditions..
