Annotation | The paper considers the process of heat propagation in an $NbN$ membrane when a current pulse passes through it based on an inhomogeneous three-dimensional thermal conductivity equation. A 3D model of the "contacts–membrane–substrate-environment" system is constructed. The maximum heating of the membrane is estimated. It is shown that the contact material (beryllium bronze BeCu) provides an effective heat sink from a superconducting membrane in a resistive state when a high-density current flows through it. |
Keywords | heat transfer, inhomogeneous heat equation, boundary value problem, beryllium bronze, $NbN$ membrane |
