Mass action law for semiconductor

  1. Sep 11, 2015 #1
    For Mass action law to hold for extrinsic material in equilibrium,
    If n goes up and p goes down for an N-type material then overall carrier concentration is the same (equal to ni_square). So why does an N-type material conducts better than a an intrinsic semiconductor (presumably they have same number of carriers) at room temperature?
