Semiconducting perovskites that exhibit superfluorescence at room temperature do so due to built-in thermal 'shock absorbers' which protect dipoles within the material from thermal interference. A new study explores the mechanism involved in this macroscopic quantum phase transition and explains how and why materials like perovskites exhibit macroscopic quantum coherence at high temperatures.
Scientists report a facile synthesis of a nanographene carbon nanosolenoid (CNS) material. The material consisted of continuous spiral graphene planes, as was typical of Riemann surface. The CNS displayed special photoluminescence and magnetic properties.
Researchers have realized integrated manipulation of magnetic skyrmions by electrical currents, including writing, erasing and addressing single skyrmions in a CoZnMn nanostripe at room temperature.
Researchers determined that interactions between electrons are what give rise to the divergent effects observed when graphene is doped with electrons versus holes.
