Abstract
The metallic micro-sized wires of gold, silver and copper with the various sizes were prepared. Their CVC, low-frequency noise, as well as the behavior and dependence of the noise spectral density on the type and sizes of metals and contacts were investigated. It is shown that the spectral density of low-frequency noise strongly depends on the dimensions of the sample. It is also shown that the spectral density of noise increases with the decrease in the diameter of the wire and with the increasing in a sample length. The dependence of the spectral density of the low-frequency noise shows that it has the contact character and is proportional to the square of the contact resistance.
