There's a range of magic angles to study superconductivity in a twisted 2D semiconductor

Дата публикации: 19-04-2026 12:00:04

Last year, tungsten diselenide (WSe2) had its magic moment. Two independent research groups discovered "magic angles" at which two atom-thin layers of the unique semiconductor, when twisted relative to one another into what's known as a moire pattern, can superconduct electricity. Cory Dean and his colleagues at Columbia documented superconductivity at a 5° twist angle; upstate at Cornell, Jie Shan and Kin Fai Mak's team saw it at around 3.5°. Until then, graphene was the only other moire material capable of the feat.
