A hole is a quasi-particle invented really to satisfy the 3rd law of mechanics, of action and reaction. A hole IS NOT an absence of an electron, and goes back to the density of (available) states argument. Above: notice the band gap, electron-volt unit, the possibility of electrons jumping from valence to conduction band (and vice-versa).

Insulator (electricity) - Wikipedia

2019-4-23 · Physics of conduction in solids. Electrical insulation is the absence of electrical conduction.Electronic band theory (a branch of physics) says that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal.If no such states are available, the material is an insulator.

Calculating Band Structure - Welcome to SCIPP

2009-4-9 · The density of occupied states per unit volume and energy, n(E), ), is simply the product of the density of states in the conduction band, gc(E) and the Fermi-Dirac probability function, f(E). Since holes correspond to empty states in the valence band, the probability of having a hole equals the probability that a particular state is not filled, so
