Inside there's a coil of wire wrapped around an iron core. When a current flows through this control wire, it creates a magnetic field. This pulls down the metal switch on top, which contacts the ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

An international team of researchers from Queen Mary University of London, the University of Oxford, Lancaster University, and the University of Waterloo have developed a new single-molecule ...

Chipmakers agree that the transistor of the next decade will actually be two transistors stacked atop one another, packing in many more devices in the same area of silicon and leading to circuits that ...

After dominating the electronics industry for decades, conventional silicon-based transistors are gradually approaching their limits, which is preventing engineers from further reducing their size ...

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 ...
