properties and parameters taken into consideration. A comparative analysis of the
calculated and measured times of interruption of the direct conduction of Yanson
point contacts suggests an enhanced chemical activity of the conduction channel
surface of these nanostructures. This peculiarity of dendritic point contacts may be
due to the size effect and the presence of a fresh metallic solid surface at the interface.
The approaches and results of the present paper can be used for the development of
selective quantum sensors based on point-contact nanostructures.
