Animal cells can use elements or ions to generate electrical impulses. These impulses are then conveyed from one cell to another, traveling across cellular networks.
In recent years, electronics engineers have been trying to broaden the pool of available semiconducting materials, to enable the development of a wider range of devices. One emerging class of semiconductors are amorphous ...
Graphene nanoribbons (GNRs) are narrow and long strips of graphene with widths below 100 nm. GNRs that have smooth edges, a sizable bandgap and high charge carrier mobility could be highly valuable for a wide range of electronic ...
In recent years, physicists and electronic engineers have been trying to identify materials that could be used to fabricate new types of electronic devices. One-dimensional (1-D) and two-dimensional (2-D) materials have been ...

Vacuum tubes initially played a central role in the development of electronic devices. A few decades ago, however, researchers started replacing them with semiconductor transistors, small electronic components that can be ...
We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook ...
(Phys.org)—Researchers have built a new type of "neuron transistor"—a transistor that behaves like a neuron in a living brain. These devices could form the building blocks of neuromorphic hardware that may offer unprecedented ...
(Phys.org)—Although vacuum tubes were the basic components of early electronic devices, by the 1970s they were almost entirely replaced by semiconductor transistors. But in the past few years, researchers have been developing ...
(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...
In electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic signals. A transistor is made of a solid piece of a semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power, the transistor provides amplification of a signal.
The transistor is the fundamental building block of modern electronic devices, and is used in radio, telephone, computer and other electronic systems. The transistor is often cited as being one of the greatest achievements in the 20th century, and some consider it one of the most important technological breakthroughs in human history. Some transistors are packaged individually but most are found in integrated circuits.
