Researchers report an insulator made of two conductors

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 material—the negatively ...

Coated zinc sulfide nanoparticles are catalytically active

Ideally, a pigment should be resistant to corrosion under light irradiation—especially to UV radiation. It should also retain its white color in the long term. Today, the industry has already achieved all this with zinc ...

A new quantum switch for electronics

A Russian physicist and his international colleagues studied a quantum point contact (QCP) between two conductors with external oscillating fields applied to the contact. They found that, for some types of contacts, an increase ...

Information transport in antiferromagnets via pseudospin-magnons

A team of researchers from the Technical University of Munich, the Walther-Meissner-Institute of the Bavarian Academy of Sciences and Humanities, and the Norwegian University of Science and Technology in Trondheim has discovered ...

Ionic defect landscape in perovskite solar cells revealed

The group of so-called metal halide perovskites as materials has revolutionized the field of photovoltaics in recent years. Generally speaking, metal halide perovskites are crystalline materials that follow the structure ...
