What is Superconductivity?
Superconductivity is a phenomenon characterized by the complete absence of electrical resistance in certain materials when cooled below a critical temperature. This allows for the unimpeded flow of electrical current, making it a highly efficient means of conducting electricity.
How Does Superconductivity Relate to Nanotechnology?
In the realm of
Nanotechnology, superconductivity is of significant interest for several reasons. At the nanoscale, materials often exhibit unique electrical, magnetic, and thermal properties that differ from their bulk counterparts. This opens up new avenues for enhancing and exploiting superconductivity in novel ways.
