Water as a metal

Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used ...

Collaboration sparks new model for ceramic conductivity

As insulators, metal oxides—also known as ceramics—may not seem like obvious candidates for electrical conductivity. While electrons zip back and forth in regular metals, their movement in ceramic materials is sluggish ...

Spectral classification of excitons

Ultrathin layers of tungsten diselenide have potential applications in opto-electronics and quantum technologies. LMU researchers have now explored how this material interacts with light in the presence of strong magnetic ...

Enhancing the performance of solar cells with 'graphene armor'

A team of researchers, affiliated with UNIST has come up with a novel electrode that could greatly improve the stability of perovskite solar cells (PSCs), the most promising candidate for the next generation solar cells due ...

How is a metal formed?

What does it mean to be a metal? How is a metal formed? These seem like textbook questions with a simple answer: Metal is characterized by free electrons that give rise to high electric conductivity. But how, exactly, is ...
