Дисперсия электронной структуры в приповерхностной области химически однородных наночастиц оксида материалов и его роль в конверсии хемосорбции энергия воды на порошке диоксида циркония

Аннотация

The electronic structure of the near-surface regions of oxide material nanoparticles of a special type and
the possibility, on this basis, to obtain specifically rectifying properties of the contact are studied theoretically and then examined experimentally. Models of surface states of the Tamm type are constructed with
taking into account the Coulomb long-range action. The discovered variance and its dependence on the
curvature of the surface of nanoparticles make it possible to study modally the conditions for the formation of a contact potential difference in the cases of nanoparticles of the same radius (synergistic effect),
different radii (doped and undoped variants), as well as to discover the possibility of describing a group
of powder particles from a given material within the Anderson model. Some consequences of the proposed concept have been examined within the experiment on the character of the current-voltage characteristics of a pair of contacting powder particles with different combinations of radii and they show the presence of properties characteristic for a rectifying contact. Prospects for further experimental tests arising from the accordance with the general theory are put forward
