At its core, computing relies on manipulating electric currents and fields. But as devices shrink to the nanometer scale, controlling these flows becomes increasingly difficult. Wires and transistors ...

This video presents the analytical solution for the electric field along the axis of a uniformly charged disk. Starting from Coulomb’s law, we derive the exact expression and discuss its physical ...

Scientists have demonstrated that other physicists' recent 'discovery' of the field effect in superconductors is nothing but hot electrons after all. A team of scientists have found new and compelling ...

Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development is one of the 20th century's key scientific milestones. Transistors work ...
