Abstract
A device includes a substrate including a first layer and a second layer. The first and second layers are positioned adjacent to each other and comprise a common boundary region extending from the first layer to the second layer. The first layer comprises graphite with a Bernal-crystal structure. The second layer comprises graphite with a rhombohedral crystal structure. The boundary region includes a border region having superconducting properties, namely; at a current density of 0 Ampere/mand a magnetic flux density of 0 Tesla exhibiting a critical temperature (T) which is higher than −195° C., and/or at a temperature below the critical temperature (T) and a current density of 0 Ampere/m, exhibiting a critical magnetic flux density (B) that is higher than 1 Tesla. The border region is coupled to an electric and/or a magnetic and/or an electromagnetic signal with a frequency greater than or equal to 0 Hertz.
