Forskare har hittat ett sätt att slå av och på supraledning i vridet dubbellagersgrafen genom att justera dess omgivning. Upptäckten utmanar konventionella teorier och kan leda till framsteg inom energieffektiv elektronik. Arbetet publicerades i Nature Physics.

Ett forskarlag lett av Chun Ning (Jeanie) Lau vid The Ohio State University kombinerade vridet dubbellagersgrafen med strontiumtitanat. Denna uppställning gjorde det möjligt för dem att finjustera hur elektroner interagerar och kontrollera supraledning genom att förändra materialets miljö. Metoden skiljer sig från traditionella angreppssätt som fokuserar på att minska elektronernas inbördes repulsion inuti själva materialet.
