Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics ...

The ultrathin topological insulator sodium bismuthide (Na 3 Bi) can switch to being a conventional insulator when an electric field is applied. This “off-on” effect, discovered by researchers in ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic circuits. Transistors are fundamental to all modern digital and analog systems.

Hardly a day goes by without a top-level research group announcing some kind of graphene-related breakthrough, but this one's a biggy: Researchers at the University of Erlangen-Nuremberg, Germany have ...
