On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this ...

The MIT team turned to chromium sulfur bromide, a two-dimensional material that acts as a magnetic semiconductor. Its structure allows researchers to switch between two magnetic states with precision.

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

A special type of matter called a Bose-Einstein condensate could be used to make tiny atomic transistors, according to research carried out by physicists in the US. The result is a first step in ...
