semiconductor physics - intrinsic concentration of charge carriers


In case of semiconductor the intrinsic charge carrier concentration N, always remains constant. This explains the decrease in number of holes when donor impurities are added to an intrinsic semiconductor and the decrease in number of free electrons when the no. of holes when acceptor impurities are added . Is there any explanation for the constancy of this intrinsic charge carrier concentration?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
