INVESTIGATION OF ELECTRIC MOULDING AND DEGRADATION PROCESSES IN MOULDED METAL - DIELECTRIC - METAL SYSTEMS

The thin-film metal - dielectric - metal (MDM) systems on base of the different materials for dielectrics and electrodes have been investigated for a purpose of studying formation and degradation nature of the moulded channels (MC) and development of the technological procedures improving the electric and operated characteristics of the MDM cathodes on base of the electric-moulded systems. The similarity and difference in the electric moulding and breakdown processes of the MDM-system have been revealed. It has been determined that the preliminary formation of the breakdown channel with certain structure and geometrical dimensions is the necessary condition for MC formation. The kinetics of the degradation processes in the electric-moulded systems has been determined, its intercommunication with degradation of the electric characteristics in the MDM-cathodes has been revealed. The positive influence of the preliminary voltage action on the dielectric of MDM-system on the moulding before application of the higher electrode in the MD-plasma and MD-electrolyte systems has been discovered. The recommendations on the increase of the emission current density and longevity of the MDM-cathodes have been given. The results are recommended to use at the enterprises of the electronic industry possessing the development of the new devices for solid-state electronics and also at the organizations studying the breakdown and ageing of the inorganic dielectricsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
