the n‐side and drift of holes from the n‐type side into the p‐side. The reverse‐bias current ( I S ) is limited by the rate at which minority carriers diffuse from the quasi‐neutral regions into the depletion region ( i.e. the rate at Similarily, a third region can be doped n-type or p-type, to form a three-terminal device. These n-p-n and p-n-p junction devices form the basis for most semiconductor devices including the transistor.

n Type Semiconductor When a small amount of Pentavalent impurity is added to a pure semiconductor providing a large number of free electrons in it, the extrinsic semiconductor thus formed is known as n-Type Semiconductor.The conduction in the n-type semiconductor is because of the free electrons denoted by the pentavalent impurity atoms. 18/10/2016 · in this video i try to explain about what is doping process, how doping is done in semiconductor with trivalent and pentavalent element and hoe p- type and n- type …
