In "Position of the Fermi Level for Extrinsic Semiconductors" the author will talk a little more in detail about doped semiconductors. Here, the author answers the following questions:
(i) What is the position of the Fermi level for an extrinsic semiconductor?
(ii) What is the concentration of electrons(holes) in the conduction(valence)
[...] Position of the Fermi Level for Extrinsic Semiconductors Additional Notes for Solid State Physics - Srijit Goswami We will talk a little more in detail about doped semiconductors. Here, we answer the following questions: What is the position of the Fermi level for an extrinsic semiconductor? What is the concentration of electrons(holes) in the conduction(valence) band? C.B EF EC ED V.B EV Figure n-type semiconductor with donor levels The following is a highly simpliﬁed treatment of the problem. We will consider n-type semiconductors, as shown in Figure Exactly the same discussion applies to p-type semiconductors. [...]
