What is it about?

We report on the nanosized effect on superconducting properties of Bi nanoparticles (NPs) that extracted from the temperature and applied magnetic field-dependent magnetization measurements of bismuth NPs, and revealed an enhanced TC and stronger coupling strength because of increased density of state and softened phonons.

Why is it important?

Our findings suggest that in addition to the size effect, the amorphous surface region could be playing an important role in defining the superconducting properties of Bi at the nanoscale.


Writing this article was a great pleasure as it helped me to understand the role of the finite size effect in the origin of superconductivity in bismuth.
