    Semiconductors and charge carriers (L-II)

    In our last lecture (L-I: lecture-I) we discussed how there are two types of charge carriers in a semiconductor; the electrons and the holes. We also discussed what are intrinsic semiconductors. i. An intrinsic semiconductor has an equal number of electrons and holes. These are produced due to thermal excitation when an electron is dislodged…
