6.13 Density of States

Fig. 6.52 Density of states
in the silicon valence(blue) and conduction-band
(red) as obtained from
theoretical calculation
using empirical
pseudopotentials. Grey
regions denotes the band
gap. Critical points (cf.
Fig. 6.9a) are labeled. In
the lower three graphs, the
DOS is decomposed into
contributions from different
angular momentum states
(s (green), p (orange) and d
(purple)). Top part adapted
from [546], bottom part
adapted from [175]
6.13.3 Free-Electron Gas
In M dimensions, the energy states of a free-electron gas are given as
Fig. 6.53 Theoretical
calculation for the density
of states of amorphous Ge
models as obtained for
various degrees of disorder
α (3.7). α = 0.09
corresponds to a mean
short-range order distance
of about 2.4 lattice
constants (cmp. Fig. 3.14b).
