Novel Superconductivity in PtBi2 Advances Quantum Technology Research

11/26/2025

Summary

Story summary

A new study by IFW Dresden shows PtBi 2 exhibits novel surface superconductivity on its top and bottom surfaces.
Surface-bound electrons in PtBi 2 pair up with six-fold rotation symmetry.
This behavior enables trapping of Majorana particles along the edges.
Researchers aim to control these properties by changing thickness or applying magnetic fields.
The findings advance understanding of topological superconductors and their applications in quantum technology.
