Instanz: TeilenTeilen:World’s first semiconductor maserRobert Emmerich Presse- und ÖffentlichkeitsarbeitJulius-Maximilians-Universität Würzburg05.08.2026 10:30Physicists at the University of Würzburg and the Würzburg-Dresden Cluster of Excellence ctd.qmat have realized the world’s first continuously operating maser based on the semiconductor silicon carbide. Spins in the semiconductor: The key to quantum functionalityThe team uses an established semiconductor material: silicon carbide. In this context, the maser functions like a ticking clock – an oscillator – whose frequency depends strongly on the surrounding magnetic field. The researchers estimate a magnetic field sensitivity of around 20 picotesla at room temperature – about one million times weaker than Earth’s magnetic field.
