A research team has successfully developed the technology to fabricate high-sensitive biosensors by simply spraying, like an inkjet printer. The technology enables the fabrication of sensitive and ...

Field-effect transistors (FETs) are the cornerstone of modern electronic devices, providing the essential functionality for digital logic, analog processing and power management.

Most transistors have three terminals, often labeled as emitter, base, and collector (in bipolar junction transistors) or source, gate, and drain (in field-effect transistors).

Field-Effect Transistors (FETs): Instead of requiring a base current, FETs use an electric field at the gate terminal to control current flowing in a channel between the source and drain.
