(Phys.org)—Due to their electronic and magnetic properties and their association with crystalline and electronic structures under extreme conditions, three-dimensional (3D) Dirac semimetals – that is, materials that possess ...
A team of researchers, led by a group at the University of California, Riverside, have demonstrated for the first time the transmission of electrical signals through insulators in a sandwich-like structure, a development ...
