Resonance charge relaxation in physical barrier layers

Abstract

It is shown experimentally that the space charge domain (SCD) of a MIS structure can be described as a layer-macrorelaxer by applying the appropriate formula for the Schottky barrier. The maximal time of the transient tC (the saturation time tCH) of the change in MIS-structure capacitance upon imposition of a sufficiently large rectangular depleting voltage pulse is expressed by the formula mentioned. A new method is correspondingly proposed for determining the ionization energy of bulk centers responsible for this relaxation. A comparison with data in the literature is presented and the prospects for developing representations on resonance charge relaxation in barrier layers is indicated.
