| Abstract(in English) | We have developed a niobium nitride superconducting mixer for terahertz band application. The NbN films are epitaxially grown with (100) direction on MgO (100) substrates, while the NbN films on Si substrate is polycrystalline. In this paper, We reported the fabrication technique of (100)-oriented NbN thin films on Si (100) wafers by DC magnetron sputtering method using TiN as a buffer layer. Moreover, the junctions consist of epitaxial NbN/AlN/NbN tunnel junctions using TiN buffer layer fabricated on single-crystal Si(100) substrates. |
