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. ...

Doubling the efficiency of organic electronics

Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just ...

Understanding the building blocks for an electronic brain

Computer bits are binary, with a value of zero or one. By contrast, neurons in the brain can have many internal states, depending on the input that they receive. This allows the brain to process information in a more energy-efficient ...

The fine-tuning of two-dimensional materials

A new understanding of why synthetic 2-D materials often perform orders of magnitude worse than predicted was reached by teams of researchers led by Penn State. They searched for ways to improve these materials' performance ...

Dawn of organic single crystal electronics

Researchers at the Institute for Molecular Science, National Institutes of Natural Sciences (Japan) have developed a method for high performance doping of organic single crystal. Furthermore, they succeeded in the Hall effect ...

Researchers attempt to explain superconductive phenomenon

Superconductivity with a high critical temperature (high Tc) presents a theoretical mystery. While this phenomenon is experimentally well established, science has not explained its mechanism. In the late 1990s, the British ...

Ultrasensitive sensor using N-doped graphene

A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing ...
