Superconducting order from disorder in 2H-TaSe 2− x S x

Condensed matter physics: crystallographic disorder enhances superconductivity Substituting sulfur into TaSe2 induces disorder, which further helps to enhance superconductivity, with a higher transition temperature. It is higher than that of either TaSe2 or TaS2. An international team of researchers...

description Condensed matter physics: crystallographic disorder enhances superconductivity Substituting sulfur into TaSe2 induces disorder, which further helps to enhance superconductivity, with a higher transition temperature.

They found that the transition temperature optimally increased when a maximal disorder is introduced by substituting sulfur into TaSe2.
