Abstract

In this comment we point out that the experimental evidence for superconductivity presented by Thapa and Pandey in arXiv:1807.08572 is also consistent with a percolation transition. We propose simple follow-up experiments which would help to eliminate percolation as a possible explanation for the observed data.

    • One case in which you can see something similar to SC transition is percolation, where the sample is mix of regular metal and insulator, and you (accidentally) connect current contacts to metal but voltage probes to insulator [1] [1] https://arxiv.org/abs/1808.05871
