Superconductive ceramics electronic devices

The re arch in catalysis is still one of the driving forces for interface science. One can certainly add to the topics of interface physics the whole new field of interface problems that is about to spring out of the new high Tc superconducting ceramics, i.e. the fundamental problem of the matching of the superconducting carriers wave-functions with the normal state metal or semiconductor electron states, the super-conductor-superconductor interfaces and so on, as well as the wide open discovery field for devices and applications. 

Because the function of semiconductors, like the new superconducting ceramics, is dependent on the way their crystalline structure is arranged, transistor makers can control the function of the devices by deliberately adding small amounts of certain impurities to the crystals. Such impurities control the flow of electricity through the device either by providing extra electrons or by not supplying enough.
