Microplasma
Microplasma device is plasma systems that generate low-temperature, non-equilibrium plasmas within confined micrometer-sized regions. These devices typically consist of two electrodes with a narrow gap, where a high voltage (DC, RF, or pulsed) is applied to ionize a working gas such as argon, helium, or air. The resulting microplasma produces a highly energetic environment with high electron temperatures but relatively low gas temperatures, enabling efficient activation of chemical reactions at near room temperature. This unique characteristic makes microplasmas especially suitable for synthesizing nanomaterials, modifying surfaces, and processing heat-sensitive materials under ambient conditions.
