Experimental study of electrone conductivity of aluminum materials contact in the presence of surface nanofilms
Annotation
The influence of $\mathrm{Al}_2\mathrm{O}_3$ nanofilms formed on the surface of $\mathrm{Al}_2$ during its oxidation on contact electrical and thermal resistances is experimentally studied. The structure of the thermal conductivity of the real contact and of the ratio of its components is considered as a function of the film properties. The advisability of determining the film conduction from the contact electrical resistance is grounded. The measured current–voltage characteristics of the $\mathrm{Al}$–$\mathrm{Al}_2\mathrm{O}_3$–$\mathrm{Al}$ system are given. The electrical and thermal resistances are computed, the constriction resistances in the contact pair of samples in experimental conditions are calculated, and the film resistances are determined. The polarity of conductivity and the height of the barrier of the $\mathrm{Al}$–$\mathrm{Al}_2\mathrm{O}_3$ contact are determined. The dependence of the heat flux through junctions with films of difference thicknesses on the electron conduction of the films is established.
