One-dimensional structure made of periodic slabs of SiO2/InSb offering tunable wide band gap at terahertz frequency range |
Transmittance through SDPC for different crystal temperatures of T = 225 K, 255 K, 285 K, and 310 K. Panels (b)–(e) are respectively the magnifications of the frequency intervals containing the first up to the fourth resonant modes. The incident angle is normal to the crystal and the thicknesses of the layers are 4 μm. |
