Abstract

Crystalline, temperature 450-600 °C (30 min). The optical parameters (N = n + ik) measured and analyzed by optical transmission spectroscopy are insensitive to the deposition parameters, provided that the films are crystalline. The dielectric properties converted from optical parameters are ε′ = 4.75 and Q = 325. The dielectric constant of BiZN thin films in THz frequency regime, (ε′)fTHz = 32, is markedly smaller than the ε′ value of BiZN bulk materials in microwave regime, and the quality factor of the thin films is less than 20% of the bulk materials. However, the dielectric constant of the thin films in THz region is still markedly larger than that derived from optical transmission spectroscopy in optical region.
