... A semiconductor is a material which has electrical conductivity between that of a conductor such as copper and an insulator such as glass. The conductivity of a semiconductor increases with increasing temperature, behavior opposite to that of a metal. Semiconductors can display a range of useful pro ...

... For centuries, people believed that electricity and magnetism were somehow related, but no one could prove a connecting link between them. Then, in 1819, the Danish physicist Hans Christian Oersted (1777–1851) discovered the connection by accident while lecturing on electric circuits at the Universi ...

... Hole theory: This theory presumes the existence of holes or vacancies randomly distributed throughout the liquid and providing ready diffusion paths for atoms and ions. The concentration of these holes would have to be very great in order to account for the volume increase upon melting, thus result ...

Electromigration
Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is important in applications where high direct current densities are used, such as in microelectronics and related structures. As the structure size in electronics such as integrated circuits (ICs) decreases, the practical significance of this effect increases.
