Direct and indirect band gap:.. This is important in physics because they are the solution of the Schrödinger's equation with periodic potential, and the source of Bloch waves.

In figure 3 an example of a chain of events in a small volume of mass dm = 1µg is shown. This electron is scattered and a bremsstrahlung photon with energy E b = 20keV is emitted

With an albedo of 0.3 and an atmosphere with a long-wavelength transmission of 0.15 and a short wavelength transmission of 0.85 we have seen that the equilibrium
