摘要
Low temperature plasmas(LTP)are typically plasmas in the gas phase with electron density from 108 cm3 to 1018 cm3,and electron temperature under 10 eV.The ionisation degree of the low temperature plasma is quite low,which means the number density of electrons is much lower than the number density of neutral particles.Another main feature of low temperature plasma is the different temperatures of various types of particles inside the plasma such as electrons,ions and neutrals.In fact the gas temperature of plasma is close to room temperature for many applications.Recently,low temperature plasmas have been used for an enormous range of practical applications,from bio-medicine and environment protection to light sources and making computer chips.The technical and commercial value of low temperature plasma is well established.The world today would be less advanced without low temperature plasmas.This greatly depends on empirical development.As the technology becomes more complex,empiricism becomes insufficient to advance the state of the art.The aim of this Special Issue is to introduce recent developments in low temperature plasma technologies on a solid scientific foundation.The Special Issue provides a high-level intellectual and scientific overview of key challenges,and discusses how meeting these challenges can improve the scientific understanding of this field,which includes.
