How does disorder change superconductor's Tc?

[mojo0529]

How does disorder (such as structure defect, doping,substitution, etc. )change superconductors' Tc?No matter what kind of superconductor it is.

Is there any resent paper exactly and detailedly discussing about this question?

Thanks in advance.

You may want to start with the classic Phil Anderson paper on "http://www.physics.umd.edu/courses/Phys798S/anlage/Phys798SAnlageSpring06/Anderson%20TimeReversed%20Pairs%20Paper.pdf" ".

I can say that disorder can have a significant impact on a superconductor's Tc (critical temperature). Disorder can refer to structural defects, doping (adding impurities), or substitution (replacing atoms in the material). These disruptions in the regular arrangement of atoms can affect the superconducting properties of the material.

One of the main effects of disorder on superconductors is the scattering of electrons. In a superconductor, electrons are able to move freely without resistance, which is what allows for superconductivity. However, when disorder is introduced, the electrons can be scattered by the defects or impurities, hindering their movement and reducing the superconducting properties of the material. This leads to a decrease in Tc.

Additionally, disorder can also disrupt the formation of Cooper pairs, which are responsible for superconductivity. Cooper pairs are formed when electrons interact with the lattice of the material. However, when there is disorder present, the lattice can be distorted, preventing the formation of Cooper pairs and reducing Tc.

The exact impact of disorder on Tc can vary depending on the type of superconductor and the extent of the disorder. Some superconductors may be more resilient to disorder, while others may be more sensitive.

There have been numerous studies and papers that have explored the effects of disorder on superconductors and their Tc. One recent paper published in Physical Review Letters in 2019, titled "Disorder-induced suppression of superconductivity in the monolayer FeSe/SrTiO3", discusses the impact of structural defects on the superconducting properties of a specific type of superconductor. However, there are many other papers and studies that have delved into this topic in detail. Further research and experimentation are still needed to fully understand the effects of disorder on superconductors and how to mitigate its impact.

I hope this response has provided some insight into how disorder can change a superconductor's Tc and the current research being done in this area.
