A pân junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The p side contains an excess of holes, while the n side contains an excess of electrons in the outer shells of the electrically neutral atoms there. This allows electrical current to pass through the junction only in one direction. The p-n junction is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy ...
ITER is an international collaboration to build the first fusion science experiment capable of producing a self-sustaining fusion reaction, as a way of generating a clean, safe, and sustainable power.
