### Degeneracy in linear tetrahedron method

In the linear tetrahedron method for the calculation of density of states, how does one circumnavigate the infinity error that would arise if two or more k-vertices of the tetrahedron have the same ...

### Motivation behind definition of density of state

The definition of density of state per unit volume stated in Girvin and Yang's Modern Condensed Matter Physics is $$\rho(E)=\int \frac{d^3k'}{(2\pi)^3} \delta(E-E')$$ I would like to gain more ...

### Show that the effective carrier density for electrons is $2\left(\frac{{m_c}^*k_BT}{2\pi\hbar^2}\right)^{3/2}$ [closed]

The 3-dimensional free electron density of states (DOS) including spin degeneracy is: $$g(E)=\frac{1}{2\pi^2}\left(\frac{2m_e}{\hbar^2}\right)^{3/2}\sqrt{E}$$ where $m_e$ is the electron mass, and $E$ ...

### Density of States

For getting the density of states formula for photons, we simply multiply the density of states for atoms by 2 (due to two spins of photons). I am getting the 2D density of states formula as :- g(p)dp ...

### Generalisation of the density states of phonons

Is it possible to generalize de density of states for phonons $\left( \left(\frac{L}{2\pi} \right )^3 \int \frac{dS_\omega}{v_g}\right)$ to a density of states which is also applicable to Bloch ...
