Normally, semiconductors don't have many free electrons. Since electric current relies on those free electrons, the amount of current that can travel through an isolated semiconductor is negligible.

This course presents in-depth discussion and analysis of metal-oxide-semiconductor field-effect transistors (MOSFETs) and bipolar junction transistors (BJTs) including the equilibrium characteristics, ...

In 1947, Shockley, Brattain and Bardeen were investigating the field effect transistor but lead them into inventing the bipolar transistor instead. In 1952, the field effect transistor of Shockley was ...

A graphene layer consists of carbon atoms linked by covalent bonds, forming a honeycomb structure. Its excellent electron mobility, chemical and physical stability, electrical and thermal conductivity ...

A field effect transistor (FET) is a carrier device with three terminals: source, drain, and gate. In FETs, an electric field can be applied at the terminal of the gate, modifying the conductive ...

On this day in tech history, JE Lilienfeld filed a patent for a three-electrode structure using copper-sulfide semiconductor material, known today as a field-effect transistor. Lilienfeld’s patent for ...

A new technical paper titled “Silicon-based Josephson junction field-effect transistors enabling cryogenic logic and quantum ...

Scientists have announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field-effect transistor (FET) with ...

A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary ...

Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...
