The title and abstract of the paper reads: Theory of Impurity Scattering in Semiconductors E. Conwell and V. F. Weisskopf Phys. Rev. 77, 388 – Published 1 February 1950 ABSTRACT Experiments by Lark-Horovitz and collaborators on the Hall effect and resistivity of germanium semiconductors have shown that the simple theory of lattice scattering alone cannot explain the temperature dependence of the resistivity. Another probable source of resistance is scattering by ionized impurity centers. This resistance can be calculated by using the Rutherford scattering formula. Evaluation of the collision terms in the Lorentz-Boltzmann equation of state is made by assuming that scattering of an electron by one ion is approximately independent of all other ions. This results in a resistivity given by (in ohm cm): (a mathematical formula) where d is half the average distance between impurity ions and κ the dielectric constant of the semiconductor.

The Conwell-Weisskopf theory was developed in 1943, over the course of only a few months. It was considered so important that it was classified as part of the war effort, and not published until 1950.
