Current transport mechanisms in metal – high-k dielectric – silicon structures

The mechanism of current transport in several high k -dielectric, including
 rare earth metal oxides (Gd₂O₃, Nd₂O₃), ternary compounds (LaLuO₃) and rare earth
 metal silicate (LaSiOx) thin films on silicon was studied using current-voltage ( I - V )
 and conductance-frequenc...

description The mechanism of current transport in several high k -dielectric, including
 rare earth metal oxides (Gd₂O₃, Nd₂O₃), ternary compounds (LaLuO₃) and rare earth
 metal silicate (LaSiOx) thin films on silicon was studied using current-voltage ( I - V )
 and conductance-frequency measurements at temperatures 100-300 K. It was
 shown that the current through the dielectric layer is controlled either by Pool-Frenkel
 mechanism of trap-assisted tunneling or by Mott’s variable range hopping conductance
 through the localized states near the Fermi level. From the results of measurements, the
 dynamic dielectric constant k of the material, energy positions and bulk concentrations of
 traps inside the dielectric layers were determined.
