a Bar of intrinsic -3 silicon having a cross-sectional area of 3x10-4 m² has an n; = 1.5×10¹6 m²³. If n = 0.14 m² /V.sand up = 0.05 m²/V.s, how long should the bar be in order that the current in it be 1.2 mA when 9 V is applied across its ends.
2.) Is the total concentration of current carriers (free electrons and holes) in a semicon- ductor equal to the concentration of valence electrons? 3.) There are two types of current carriers in semiconductors (free electrons and holes) and only one type in metals. Yet, metals are much better conductors of electric current. Is this because the currents of electrons and holes oppose each other?
