When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated ...

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature. The ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Sun et al. selectively excited surface-carriers in topological insulators by directing circularly polarized light at oblique incidence on the surface of the crystal. They determined the resulting ...

The need to integrate renewable energy resources, and prepare for increased demand for power as electrification takes hold in transportation and other sectors, creates challenges for an aging grid.

A perfect insulator, or a material that reflects heat while absorbing none of it, has been created by scientists at the Massachusetts Institute of Technology and Sandia National Laboratories. Besides ...

Scientists have uncovered the detailed structure of the aluminum oxide surface, a challenge that has baffled researchers for decades. Scientists at the TU Wien and the University of Vienna have ...

Insulator or superconductor? Physicists find graphene is both, at a 'magic angle.' It's hard to believe that a single material can be described by as many superlatives as graphene can. Since its ...

More than a century after the cable-style “Mickey Mouse” insulator was introduced, a Chicago-area lineman has introduced a new take on the vintage porcelain insulators. “Linemen love the Mickey Mouse ...
