Suppose holes in a particular semiconductor have mobility h = 480 cm/Vs and electrons in this semiconductor have mobility = 1350 cm/Vs. p = 4.63 x 1013 cm- and n = 1.13 x 1015 cm- are the densities of electrons in the conduction band and holes in the valence band. (a) Calculate the total conductivity of the semiconductor. (b) Show that, independent of doping, the minimum conductivity that can be achieved is o = 2e nintrinic eh. (c) Calculate the minimum conductivity of the semiconductor. (d) Calculate the value of p- n when minimum conductivity is achieved.
