Abstract
Analysis of the current response to a pulsed perturbation of the poten tial under potentiostatic conditions makes it possible to investigate the kinetics of the formation and displacement of ionic space charge i n thin surface films (<20 nm) with high sensitivity with respect to th e mass or Charge (10(-8) g/cm2 or 10(-5) C/cm2) and with good time res olution (<10(-4) sec). The formation of mobile anions and cations in o xide films of electrochemical valve metals has been considered as an e xample.
