A transistor is a tiny device that either switches electric current on and off or amplifies an electric current. The original transistors were small cylinders, a bit larger than a pencil eraser.

These electrons are zippy and help the transistor switch rapidly, but they also tend to travel up towards the gate and leak out. To prevent them from escaping, the device can be capped with a ...

This transistor could amplify electrical signals, but not particularly complicated ones. If the signal changed rapidly, as a voice coming over a phone line does, the transistor couldn't keep up ...

Transistors made of cellulose nanoparticles offer a carbon-neutral approach to constructing electronic devices.

This technology, known as a "synaptic transistor," mimics the architecture of the human brain — in which the processing power and memory are fully integrated and found in the same place. This ...

Researchers at the Manisa Celal Bayar University in Turkey have proposed using a skived-type aluminum heat sink (HS) to cool insulated gate bipolar transistor (IGBT) arrays in solar PV inverters.

Making A Transistor Radio was published in 1972, and appeared as a second edition in Ladybird’s Learnabout series at the end of the decade.
