The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

The paper shows by calculation that the diffusion of nickel even for 50 years does not lead to degradation of thermoelectric generator modules. In the process, we used the theory of composites to calculate the electrical contact resistance, our own diffusion theory of electrical contact resistance, as well as the method for approximating the temperature dependences of thermoelectric material characteristics from the experimental data. When using the above method, it was assumed that the main mechanism of scattering of free charge carriers in a thermoelectric material is their scattering on the deformation potential of acoustic phonons with a free path length independent of energy but inversely proportional to temperature, and the main mechanism of phonon scattering is phonon-phonon scattering with Umklapp, which is not affected by the nickel impurity in the thermoelectric material. Thus, it was believed that the role of nickel is reduced only to a change in the concentration of free charge carriers in the material.
