Abstract: A simulation of the temperature distribution in a functional NbN nanoelement with a built-in normal metal region has been carried out. The functional element consists of two NbN nanowires with a thickness of 4 nm, located on a substrate of monocrystalline Al$_2$O$_3$. The wires are separated by a 10 nm thick dielectric layer. A region of normal metal is embedded in the lower nanowire using the ZA technology. An approximate estimate of the performance of functional nanostructures, for the creation of which such a hike is used, is given.

Keywords: thin superconducting NbN films, functional superconducting nanoelements from NbN, modeling of thermal processes.
