Surprising electronic disorder in a copper oxide-based ceramic

Cuprates, a class of copper-oxide ceramics that share a common building block of copper and oxygen atoms in a flat square lattice, have been studied for their ability to be superconducting at relatively high temperatures. ...

Superconductors: Resistance is futile

Every standard cable, every wire, every electronic device has some electric resistance. There are, however, superconducting materials with the ability to conduct electrical current with a resistance of exactly zero – at ...

Researchers capture an image of negative capacitance in action

For the first time ever, an international team of researchers imaged the microscopic state of negative capacitance. This novel result provides researchers with fundamental, atomistic insight into the physics of negative capacitance, ...

New class of solar cells, using lead-free perovskite materials

Lead-based perovskites are promising materials for low-cost and high-efficiency solar cells. However, the intrinsic instability and the toxicity of lead (Pb) have raised serious concerns of the viability of Pb-based perovskites, ...
