There is no doubting the contribution made to everyday life of semiconductors, used mainly as components for radio receivers, televisions and cell phones, over the last 50 years or so.

But now physicists can barely contain their excitement over the expected contribution of superconductors.

Superconductivity basically refers to the electric resistance of a material suddenly being reduced to zero under certain circumstances, said Zhao Zhongxian, a superconductivity physicist and member of the Chinese Academy of Sciences.

With components made of superconductors, the accuracy of atomic clocks on satellites will be enhanced, central processing units on computers will be accelerated and the precision of gyroscopes on navigation devices will be increased.

Despite the wide range of possible applications for superconductors, physicists, however, used to believe that superconducting properties only worked at temperatures no higher than – 233 C.

In 2008, Japanese scientist Hideo Hosono achieved a breakthrough by discovering an iron-based superconductor that functions at much warmer temperatures.

Chinese scientists later discovered even better-performing superconductors.

“You might think –218C is still a very low temperature, but it is relatively ‘warm’ and is already possible for industrial use,” said Wang Nanlin, a researcher from the Institute of Physics, Chinese Academy of Sciences.

“Now a superconductivity cable with a diameter of a pen allows transmission of a 10,000 amp current without any loss of electricity.”
