su•per•con•duc•tiv•i•ty  (so̅o̅′pər kon′dək tiv′i tē), n. [Physics.]

1. Physics the phenomenon of almost perfect conductivity shown by certain substances at temperatures approaching absolute zero. The recent discovery of materials that are superconductive at temperatures hundreds of degrees above absolute zero raises the possibility of revolutionary developments in the production and transmission of electrical energy.
