Title: Breakthrough in the production of multilayered van der Waals superconductor heterostructures
An international team of researchers has made important progress in the production of multilayered van der Waals superconductor heterostructures. This groundbreaking study, published in the renowned journal Nature, offers opportunities for the development of future functional units and applications.
Van der Waals heterostructures have attracted considerable attention in recent years. With thousands of two-dimensional materials that can be stacked in various combinations, the possible applications are seemingly endless. But until now, the production of these heterostructures has not been scalable for practical applications.
The team developed an innovative method to overcome this challenge. They developed a high-to-low temperature strategy for the controlled fabrication of stacks of multilayer van der Waals superconductor heterostructures (vdWSH) at the wafer level. The number of layers of two-dimensional superconductors in the vdWSHs can be precisely controlled. 27 double, 15 triple, 5 quadruple, and 3 quintuple vdWSH films have already been produced, with each block representing a 2D material.
Detailed morphological, spectroscopic, and structural analyzes confirmed the presence of parallel, clean, and atomically sharp vdW interfaces on a large scale, with minimal contamination detected between adjacent layers. These intact vdW interfaces enable the creation of proximity-induced superconductivity and superconducting Josephson junctions in the centimeter range.
The possibilities of producing multilayer vdWSHs can be easily transferred to other situations with two-dimensional materials. This could accelerate the development of next-generation functional devices and a variety of applications.
This breakthrough in the fabrication of multilayered van der Waals superconductor heterostructures will delight experts and researchers in the field of naturopathy. The resulting developments could lead to new therapies and treatments based on the unique properties of these materials.
