Density of States - gatech.edu

2006-1-4 · Derivation of Density of States (0D) When considering the density of states for a 0D structure (i.e. quantum dot), no free motion is possible. Because there is no k-space to be filled with electrons and all available states exist only at discrete energies, we describe the density of states for 0D with the delta function. Thus, g(E)0D =2δ(E−Ec)

An investigation of the porous silicon optical absorption

2019-5-13 · process. we derive the relation between the absorption coefficient and the averaged conduction density of states near the band edge for porous silicon. By postulating a specific form for the effective conduction density of states we find excellent agreement with recent optical absorption data for p-type doped porous silicon.
