Room temperature permittivity and carrier concentrations.

Wavelength dependence of the (a) real and (b) imaginary permittivity of Al:ZnO (1:20 ratio) films containing low (69 nm) to higher (577 nm) thickness. (c) Thickness dependence of crossover wavelength, λc and calculated carrier concentration using the Drude-Lorentz model. (d) Dependence of measured carrier concentration (ne) and sheet carrier density (ns) of AZO films.
