We know that superconductors provide three extraordinary powerful
features - zero resistivity, perfect diamagnetic, and Josephson Effect, which
are a vital enhancement of functionality in electrical, magnetic, and quantum
mechanics fields, respectively.
Zero resistivity of a superconductor directly change
the essential electrical relation of current, voltage and energy dissipation in
a device, which will lead to a new era of revolution in electronics. Its
bottomless benefits are still yet to be fully materialized. However, it
definitely brings advantages in low energy consumption, power efficiency and
even in device’s endurance.
Superconducting magnetism is one of the most striking
electromagnetic phenomena known. In superconducting state, a superconductor is
perfectly diamagnetic where the interior of superconducting material expulses
external magnetic field. This phenomenon (which is named Meissner effect) is
deviated from the classical theory of ‘prefect conductor’. This characteristic
is totally unexpected before the discovered of superconductor.
Superconductor is one of a few macroscopic materials
that manifest quantum mechanics behaviors. Josephson Effect is a fascinating
quantum tunneling phenomenon where supercurrent tunnels through an extremely thin
insulator. This effect is currently being employed in the building block of
SQUIDs. Josephson effect is also adopted by some high-end research like quantum
computing and photon detection.
Despite having much discussed above, superconductors
are still far from fully comprehensive. Particular properties of superconductor
are still keeping discovering. The instances, the Tao effect, the de
Heer effect, and the rotating superconductor. Last but foremost,
superconductor brings new aspect of ideas, integrating different aspect of knowledge
provides a wide range of innovation and invention, of for blinking science and
technology progress.
