| Popis: | We demonstrate the broadband THz antireflection coating based on bismuth nanofilms. The antireflection effect stems from the complex-valued conductivity of bismuth, providing excellent impedance matching with high-index dielectrics such as silicon, in the range of at least 0–4 THz. The details of THz conductivity of bismuth will also be presented. |
