The MOSFET in Figure 1 is used as both a heater and a temperature sensor in a thermostatic circuit. Figure 1 Circuit diagram for using a MOSFET as a thermostatic heater. The circuit can be used as 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 . . .

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 ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

A transistor – a word blend of "transfer" and "resistor" – is a fundamental component of today's advanced electronics. Essentially, a transistor, as one of the foundational elements of modern ...

A RIKEN study shows that squeezing the right amount of potassium ions between the atomic layers of molybdenum disulfide can turn it from a semiconductor into a metal, superconductor or insulator. The ...

The ever-shrinking features of transistors etched in silicon have always required pushing the cutting edge of manufacturing technology. The discovery of atomically thin materials like graphene and ...
