Breakthrough Method Unlocks High-Temperature Topological Superconductors

2/10/2026

Summary

Story summary

Researchers from the University of Chicago and West Virginia University control exotic quantum states in iron telluride selenide by adjusting tellurium-to-selenium ratios, enabling a topological superconducting state.
The method tunes electron interactions and makes device fabrication easier by using thin films instead of bulk crystals.
Thin films operate at higher temperatures than bulk crystals.
Nature Communications published the findings, opening new avenues in quantum materials research.
