In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.

A research group measured the magnetoresistive effects -- change in conductivity in response to an applied magnetic field -- using palladium-cobalt oxide (PdCoO₂), a non-magnetic, highly ...

IGBT, stands for Insulated Gate Bipolar Transistor. It is a bipolar transistor with an insulated gate terminal. It combines a control input with a MOS structure and a bipolar power transistor in a ...

CARBON nanotubes can be switched from acting like a semiconductor to acting like a metal and back again simply by using a magnetic field. This fulfils a prediction based on one of the most fundamental ...

Conductors are materials that allow electric current to flow with minimal resistance and are essential for transmitting power and electrical signals in electronic devices. Most metals are good ...
