1.08 Extrinsic semiconductor. To produce extrinsic semiconductor material specific amounts of impurity are added to the pure intrinsic semiconductor. This process is called doping and the impurity atoms are called donor atoms.There are two types of extrinsic semiconductor which are manufactured, P type semiconductor and N type semiconductor.his process is called doping and the impurity atoms are called donor atoms. There are two types of extrinsic semiconductor which are manufactured, P type semiconductor and N type semiconductor.
Carrier recombination and generation. Recombination of electrons and holes is a process by which both carriers annihilate each other: electrons occupy-through one or multiple steps-the empty state associated with a hole.Both carriers eventually disappear in the process..8.2. Band-to-band recombination depends on the density of available electrons and holes. Both carrier types need to be available in the recombination process. Therefore, the rate is expected to be proportional to the product of n and p.
