MODES OF ELECTROSTATIC DEPOSITION OF FEMTOLITER DROPLETS ON ELECTROD-HOLDER
Abstract
For reduced pressure 60–300 Torr experimental results and theoretical estimates of electrostatic deposition of femtoliter droplets, containing inside nanoparticles, from the gas stream on substrate-electrode are presented. It is shown that the corona discharge with a stream of droplets is stable in a limited range of currents and voltages. Similarity criterion of the process of electrostatic deposition is obtained. It was found that the use a thin dielectric substrate, covering the electrodes, significantly reduces agglomeration of charged droplets due to Coulomb repulsion.
