This invention discloses a method for controlling the thermal relaxation path of superconducting nanostructures and its application. This method utilizes a van der Waals integration strategy to sequentially fabricate a molybdenum disulfide layer on a silicon / silicon oxide substrate using chemical solution deposition and a niobium nitride superconducting layer using magnetron sputtering, constructing a niobium nitride / molybdenum disulfide heterostructure with intrinsic anisotropic thermal conductivity. Superconducting nanodevices with specific geometric configurations are designed for this heterostructure. Leveraging the ultra-high in-plane thermal conductivity of molybdenum disulfide and its suppressed out-of-plane heat transfer characteristics, the method achieves directional control of the internal thermal relaxation path of the superconducting nanostructure, verifying its dual advantages of optimizing thermal management and enhancing superconducting performance. The control method of this invention is mature and controllable, effectively transforming disordered thermal relaxation into directional heat transfer, significantly improving the thermal stability and integration density of superconducting devices, and providing a core solution for the thermal management of nanocircuits in fields such as superconducting quantum computing and high-sensitivity quantum detection.

This invention belongs to the field of advanced manufacturing technology and relates to an electro-spraying method for inducing jets with pre-printed functional layers. Based on electrohydrodynamic effects, a jet is ejected to pre-print complex micro / nano functional structure patterns on a substrate. Then, under the action of an electric field, the jet size and deposition position are induced. Dual nozzles work together to rapidly achieve the same shape as the pre-printed functional layer. The pre-printed functional layer fully adheres to and solidifies with subsequent nanoscale continuous jets, forming a composite micro / nano functional structure. This electro-spraying method uses a pre-printed functional layer to change the distribution of the electric field on the substrate, ensuring the accuracy of the jet deposition position and reducing dimensional errors in the composite micro / nano functional structure process. It has advantages such as low equipment cost, simple process, and short processing cycle, optimizing the micro / nano functional structure and improving the performance and lifespan of nanodevices.
