... For = 11.7, T = 300 K and W0 = 0.05 eV Eq. (8) yields n c = 1.96410 19 1/cm 3 . This is rather a high concentration of delocalized electrons. It requires the same value of a concentration of donor impurity atoms (in this case average distance between the impurity atoms is 3.7110 7 cm). Atomic v ...

Notice that when the forces are balanced, the object might still be moving, but the objects are not accelerating, instead they have a constant velocity.
