A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...

It might look like a roll of chicken wire, but this tiny cylinder of carbon atoms -- too small to see with the naked eye -- could one day be used for making electronic devices ranging from night ...

Unlike conductors such as copper, which allow electricity to flow freely, or insulators such as rubber, which block ...

Conductors are materials that allow electric current to flow with minimal resistance and are essential for transmitting power and electrical signals in electronic devices. Most metals are good ...

Researchers at the University of Birmingham have developed a vibrational exfoliation technique that enables scalable, ...

At the heart of the semiconductor industry are materials that exhibit conductivity between that of a conductor and an insulator, depending on conditions. Silicon, the most prevalent semiconductor ...

A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and ...

A new method for combining magnetic elements with semiconductors—which are vital materials for computers and other electronic devices—was unveiled by a research team led by the California NanoSystems ...

Scientists at Duke University have developed a method that switches a carbon nanotube from acting like a metal to acting like a semiconductor and back again, by wrapping it with a ribbon-like polymer.
