i the procedure of ejection of electrons from a metal surface by the application of heat is known as thermionic emission and emitted electrons are
it is based on the photovoltaic effect one of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and
at high reverse voltage due to high electric field the minorities charge carriers while crossing the junction acquires very high velocities a chain
when reverse bias is enhanced the electric field at the junction also enhances at some stage the electric field becomes so high that it breaks the
as electron hole pair because of thermal collisions is continuously formed in the depletion region these are a regular flow of electrons in the
because of concentration difference holes or electron try to vary from their side to other side only these holes or electrons cross the junction
