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 ...

An Australian-led study has found unusual insulating behavior in a new atomically-thin material—and the ability to switch it on and off. Materials that feature strong interactions between electrons ...

Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

Diamond is an effective electrical insulator, but that might not always be the case according to a new study from MIT and Nanyang Technological University (NTU) Singapore. The team has calculated that ...

A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material ...

Ohm's law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

Tantalum disulfide is a mysterious material. According to textbook theory, it should be a conducting metal, but in the real world it acts like an insulator. Using a scanning tunneling microscope, ...

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.
