Explicit expression for Lindhard dielectric function at finite   temperature
  In this work, within the scope of the Lindhard dielectric function formalism for the homogeneous electron gas, explicit expressions for the real and imaginary parts are calculated for finite temperature. An application to Raman scattering in n-type GaAs is presented to highlight the power of the method
