Problems solved by technology

[0005] For the commercial application of atmospheric pressure plasma, the biggest problem is that the feeding efficiency is too low
For example, in an arc plasma, once the arc is formed, the voltage across the electrodes drops rapidly, causing a subsequent drop in the energy density in the plasma

Abstract

The invention discloses a surface coupling induced ionization technology, which comprises any one of the following steps of: (1) feeding a first beam of electromagnetic wave into a material through afree space or a waveguide to excite a surface plasma wave; introducing target molecules to be ionized into the surface of the material, coupling electrons of the target molecules with surface plasmonpolaritons on the material by controlling interaction, and inducing the target molecules to be ionized; (2) synchronously passing through a free space or a waveguide, and then feeding a second beam and subsequent electromagnetic waves into an ionization region of target molecules on the surface of the material, so that the ionized target molecules are absorbed, and the ionization degree of the target molecules is improved; and (3) releasing the target molecules in the form of bulk phase plasmas to realize surface coupling induced ionization. The invention also discloses a plasma device.

Description

technical field [0001] The invention relates to the fields of material science and electronic devices, in particular to plasma and ionization. In addition, the present invention also relates to a series of plasma devices involving the above-mentioned plasma. Background technique [0002] Plasma is a state of matter formed after further ionization of gaseous molecules under the action of an external field or heat. There are many common plasmas in life, including high-temperature flames in combustion environments, arcs formed when high-voltage discharges break down air, and colorful neon lights in streets and alleys. The technology of converting gaseous molecules into plasma, that is, ionization, is widely used in various fields such as waste treatment, rubber recycling, material synthesis and material surface modification, detection and analysis. [0003] Different forms of plasma have different ionization conditions, but the most common is the plasma formed under negative ...
