| Abstract: | A general expression is obtained for the thermodiffusion coefficientD
T of a film, also for its dependence on temperature, film thickness and type of concentration distribution of the interstitials,
according to its profile. In neglecting interaction of interstitials with each other in a model of a film with single-plane
boundaries with the vacuum and the substrate, it is shown thatD
T>D
T
(∞) is possible, whereD
T
(∞) is the thermodiffusion coefficient of a bulk specimen.
