  Abstract:
We have investigated the effect of finite non-magnetic impurity doping concentration on the critical temperature (Tc) of the MgB2 superconductor by using the coherent potential approximation. We found, by choosing the chemical potential μ = −0.47t and scattering strength δ = 4.5t, that Tc is reduced with impurity concentration similarly to the measured experimental results.
