Method for obtaining platform for testing chemical substances by the technique of surface strengthened Raman spectroscopy and platform obtained by this method

摘要

the subject of the invention is a way to receive platform research chemicals enhanced surface raman spectroscopy technique, containing surface layer of highly extensive acting zinc oxide surface on a silicon substrate and covered with a layer of an embedding gold, characterized by that,the first pre preparing silicon substrate; subsequently, such substrate is subjected to a deposition (so-called atomic layers.ald method), where, as a result of the chemical exchange reaction process occurs the deposition layers of zinc oxide, which operates in a cyclical manner, with the use of oxygen zinc precursor and gas remaining liquid, whereby the thickness of layers is determined number of ald cycles.resulting in an silicon substrate coated with a layer of zinc oxide with well developed morphology surface, such that the standard deviation of surface roughness (ang. root mean square rms) exceeds the value of 60 nm, after which the so obtained substrate silicon coated with a layer of zinc oxide is inscribed gold pvd method (ang.physical vapor deposition physical deposition from the gaseous phase). in addition, the invention includes a platform so obtained.
