minoritetsbärarlagring
Minoritetsbärarlagring is a term used in semiconductor physics to describe the process of storing charge carriers of the minority type within a semiconductor device. In a semiconductor, the two types of charge carriers are electrons and holes. In an n-type semiconductor, electrons are the majority carriers and holes are the minority carriers, while in a p-type semiconductor, holes are the majority carriers and electrons are the minority carriers.
When an excess of minority carriers is injected into a semiconductor region, for example, through a forward-biased
A key example of minoritetsbärarlagring is observed in bipolar junction transistors (BJTs) and diodes. During switching
