The 2N3819 is the archetypal general-purpose N-channel FET. (ON Semiconductor)Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor.

N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to open. P-FETs are like PNP transistors, too – the gate pin of a P-FET needs to ...

Using a new fabrication technique, engineers have developed a diamond field-effect transistor (FET) with high hole mobility, which allows reduced conduction loss and higher operational speed. This ...

FET Preamp Circuit diagram and schematic. The circuit is a sensitive preamplifier using an N-Channel FET and a PNP transistor. This combination gives high input impedance and low output impedance with ...

The result was the world’s first working n-channel MOSFET transistor made using diamond. The researchers then put the transistor through a series of tests to check for conductivity performance.

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

Using a new fabrication technique, NIMS has developed a diamond field-effect transistor (FET) with high hole mobility, which allows reduced conduction loss and higher operational speed. This new ...

The team confirmed that the fabricated diamond MOSFET actually functioned as an n-channel transistor. In addition, the team verified the excellent high-temperature performance of the MOSFET as ...

In early testing, a vacuum-channel transistor was able to operate at 460GHz -- on the order of 10 times faster than a conventional, silicon-based FET (and comparable to the speeds that a graphene ...

At the December 2021 IEDM conference (a conference for people who design advanced semiconductors), IBM announced it was turning transistors on their heads to keep Moore’s Law scaling alive.
