Conceivably, an electron and a hole in germanium could form astable holeium state, in which they orbited around their commoncenter of mass in a manner similar to a Bohr hydrogen atom. Whatwould be the rough size of an "atom", and what would be itsionization energy? At what maximum temperature would be expected toobserve such a state?
The effective mass of electrons in Ge is: m*/mass(of electron) =0.12. The effective mass of holes in Ge is m*/m(of electron) =0.21. And the dielectric constant of Ge is k=16.0.
