Using a laser to stimulate a photocurrent and a magnetic field to control it, researchers have devised a scheme for measuring a current’s flow stream. Why there’s a need to assess current-flow ...

While theoretically the ideal semiconductor, diamond has not yet become mainstream in transistors and other components. Researchers have fabricated a diamond field-effect transistor (JFET) with a ...

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 ...

A Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is a fundamental building block of modern electronics. It is a field-effect transistor (FET) where the voltage applied to a terminal (gate) ...

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 ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...
