Analytical model of electric field assisted ion diffusion into glass containing two indigenous mobile species, with application to poling

An analytical model of electric field assisted diffusion ions into glass is extended to include two indigenous mobile ion species that are initially uniformly distributed within the glass. A quasi-stationary state solution includes effects and applicable when invasive have a lower mobility than presented. It relevant electrical poling soda-lime borosilicate glasses with concentrations (Na + , K ) processed non-blocking anode where hydrogen injection occurs. The compared numerical solutions based on drift-diffusion equations Poisson's equation shows good agreement. increase in concentration (K below poled layer pile-up region accurately modelled.
