Changes in the electronic states of slabs are investigated depending on the number of monolayers and the concentration of defects. The tendencies in the formation of the total density of electronic states curve during the transformation from a monolayer to a bulk sample for gold are of a similar character. Monolayer nanostructures of gold were studied experimentally on the silicon surfaces (111) and (110) by tunneling microscopy and spectroscopy using a high-vacuum tunneling spectrometer with atomic resolution JSPM-4610 (JEOL, Japan) Svitlana Smolyak(Kurdyumov Institute for Metal Physics of the NAS of Ukraine)Kurdyumov Institute for Metal Physics(NAS of Ukraine)
