  • Conductivity and mobility in semiconductors, L-III

    Conductivity and mobility in semiconductors, L-III

    We will discuss in this lecture about drift velocity of electrons and holes in semiconductors which leads to the conductivity and mobility of free charge carriers in the same. To smooth-sail through this lecture you might wanna first brush up the concepts discussed in the last two lectures: lecture I and lecture II. Lets begin…

  • Semiconductors and charge carriers (L-II)

    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…
