Regular on/off switches rely on fingers and springs to bring bits of wire together or apart. When the wires touch, electrons flow from one to the other, and your computer/nightlight/sock warmer is on.

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...

A transistor is an element that amplifies electrical signals and controls the on/off of currents by electrical signals. Transistors are necessary parts for assembling logic circuits, and it is no ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the ...

The companies announce a new 'VTFET' transistor design to help sustain Moore's Law for years to come. To take chip designs to the next level, IBM and Samsung are researching how to build semiconductor ...

A bioelectronic engineer, Klas Tybrandt of Linkoping University in Sweden, has built the first "ion transistor" computer chip, which uses chemical ions and biological molecules as charge carriers ...

MIT engineers built a magnetic transistor from chromium sulfur bromide, promising smaller, faster electronics with built-in ...

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 ...

To take chip designs to the next level, IBM and Samsung are researching how to build semiconductor transistors vertically to free up more space on the silicon. The research has led the companies to ...
