  • 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…
