PORTLAND, Ore. — Expensive optical-to-electronic-to-optical converters are needed to switch photonic signals. Now, researchers have demonstrated an excitonic transistor that can perform the operation ...

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 ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch 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 . . .
