Question

Difference between density of states and effective density of states

Answer 1

here is your answer mate :-

The density of states function describes the number of states that are available in a system and is essential for determining the carrier concentrations and energy distributions of carriers within a semiconductor. In semiconductors, the free motion of carriers is limited to two, one, and zero spatial dimensions.

The effective density of states for electrons in the conduction band is calculated from: and the effective density of states for holes in the valence band is obtained from: The intrinsi carrier density is then obtained from both effective densities
