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 ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature switching performance that silicon struggles to match at similar scales. The ...

Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. With just three transistors, one ...

Computer engineering, but in particular mobile computer engineering, is all about playing a zero-sum game with yourself. Power and efficiency are constantly undercutting one another, creating ...

We like to pretend that our circuit elements are perfect because, honestly, it makes life easier and it often doesn’t matter much in practice. For a normal design, the fact that a foot of wire has a ...

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 . . .

Saswato R. Das writes about physics and astronomy. A little electronic device that triggered one of the most dramatic technological explosions in history turns 60 on Sunday. The humble transistor and ...

As Moore's Law slows, people are starting to look for alternatives to the silicon chips we've long been reliant on. A new optical switch up to 1,000 times faster than normal transistors could one day ...
