What is the solution of Dirac delta function of density of sate equation below: DOS(E)=2/N ∑ ∫(1/dE_{j}(k)/dk).δ[Ej(k)-E]dE
Hi,you can use " tex formula tex " to eidt your formula as follows [tex]\frac{1}{2}Ax= b[/tex] and state your problem clearer.
This is basically the density of state at energy E from N_hex bands. The delta function filters out the energy spectrum at E_j(k_t)=E. 1/|dE/dk| gives density of state at E from the given band
Do you mean the final equation become like this DOS(E)=E. 1/|dEj/dk| please do you have a reference of this solution ?
