WebSep 12, 2024 · The density of holes, or the number of holes per unit volume, is represented by p. Each electron that transitions into the conduction band leaves behind a hole. If the conduction band is originally empty, the conduction electron density p is equal to the hole density, that is, n = p. Figure 9.7. 1: The motion of holes in a crystal lattice. WebDec 29, 2010 · The number density of free electrons (the number of free electrons per unit volume, n) depends on the choice of metal. In Drude’s model, the valency of a metal is simply the number of free electrons released per atom. For example, the valency of aluminium is three, so each aluminium atom releases three of its 27 electrons into the electron gas. free books by african american authors
