RESUMO

The change of thin metallic film electrical conductivity with a impurity concentration gradient is numerically obtained. We use the Fuchs-Sondheimer approach to solve the Boatsmann equation, introducing boundary conditions imposed by the external surfaces. The effect of impurities, wich diffuse into the film from it s surface, is included directly in Boatsmann equation trough a variable relaxation time, that depends on the local impurity concentration.
