Abstract
The divergence at small scattering angles for unscreened charged-impurity scattering may be removed by including the probability that a closer scattering centre does not exist. This introduces an exponential function like the screening factor, which allows a straightforward bridging to be made between non-screening and screening situations. An expression for the mobility which encompasses the Conwell-Weisskopf and Brooks-Herring results is derived.Keywords
