Invented the world's smallest superconducting material

On March 29, scientists at the University of Ohio found the world's smallest superconducting material - a chain of four pairs of molecules of 3.5 nanometers.

The invention is published in the online edition of the journal Nanotechnology.

The superconducting compound is made by combining the atoms of an organic salt (BETS) ₂ -GaCl ₄ on the surface of silver and then cooling it down to 10 degrees K (minus 263 degrees Celsius).

Through the spectral scanner, the atomic strings can be divided into different lengths.

However, the limitation of this material is that superconductivity will decrease if temperatures rise so scientists will continue to study alternatives.

Previously scientists have asserted that it is nearly impossible to make superconducting materials from metal bonds at the nanoscale because their resistance will increase if the size is small, resulting in melting and breaking. complete harm.

Professor Saw-Wai Hla of the University of Ohio's Institute of Quantum Physics and Nano, who led the research, said that this was the main barrier to the creation of nanoscale electronics. .

Superconducting materials were first invented in 1911, which were highly conductive due to the resonance of almost zero and were often used in high-tech industries.

The invention of superconducting materials at nanometer size is a condition for the manufacture of microelectronic devices for energy applications.
