Question

What do you mean by majority and minority carriers in extrinsic semiconductors?

Expert Solution

Step 1

A small amount of a suitable impurity is added to the pure semiconductor; the conductivity of the semiconductor is increased. Such materials are known as extrinsic semiconductors. The extrinsic semiconductors are mainly of two types, n–type semiconductors and p–type semiconductors.

exist is for valence electrons to "leap" into the conduction band with the Enoiteou Question 5 pplication of sufficient energy, legving a hole, or vacancy, behind in the valence band: Valence electron leaping into conduction band Conduction band valence band With sufficient thermal energy, these electron-hole pairs will form spontaneously. Af room temperature, however, this activity is slight. we may greatly enhance charge carrier formation by adding specific impurities to the semiconducting material. The energy states of atoms having different electron configurations do not precisely "blend" with the electron bands of the parent semiconductor crystal, causing additional energy levels to form. Some types of impurities will cause extra donor electrons to lurk just beneath the main conduction band of the crystal. These types of impurities are called pentavalent, because they have 5 valence electrons per atom rather than 4 as the parent substance typically possesses: Doped with a…
