Abstract

Przedmiotem wynalazku jest sposób otrzymywania platformy do badań substancji chemicznych techniką wzmocnionej powierzchniowo spektroskopii Ramana, zawierającej powierzchnię stanowiącą warstwę tlenku cynku o wysoce rozbudowanej powierzchni osadzoną na podłożu krzemowym i pokrytą warstwą złota, charakteryzujący się tym, że najpierw wstępnie przygotowuje się podłoże krzemowe; następnie takie podłoże poddaje się procesowi osadzania warstw atomowych (tzw. metoda ALD), gdzie w wyniku chemicznej reakcji wymiany zachodzi proces osadzania warstw tlenku cynku, który prowadzi się w sposób cykliczny, z użyciem prekursora tlenowego, prekursora cynku i gazu płuczącego, przy czym grubość otrzymanej warstwy jest zdeterminowana ilością cykli ALD, w wyniku czego otrzymuje się podłoże krzemowe pokryte warstwą tlenku cynku o silnie rozwiniętej morfologii powierzchni, takiej, że wartość odchylenia standardowego chropowatości powierzchni (ang. Root Mean Square, RMS) przekracza wartość 60 nm, po czym na tak otrzymane podłoże krzemowe pokryte warstwą tlenku cynku nanosi się złoto, metodą PVD (ang. Physical Vapor Deposition - fizyczne osadzanie z fazy gazowej). Ponadto wynalazek obejmuje tak otrzymaną platformę.The subject of the invention is a method for obtaining a platform for testing chemical substances by surface enhanced Raman spectroscopy, comprising a surface constituting a layer of zinc oxide with a highly developed surface deposited on a silicon substrate and coated with a layer of gold, characterized in that the silicon substrate is first pre-prepared; then such a substrate is subjected to the process of atomic layer deposition (so-called ALD method), where as a result of a chemical exchange reaction the process of deposition of zinc oxide layers occurs, which is carried out in a cyclical manner, using an oxygen precursor, zinc precursor and scrubbing gas, the thickness being the obtained layer is determined by the number of ALD cycles, resulting in a silicon substrate coated with a layer of zinc oxide with a highly developed surface morphology, such that the value of the surface roughness standard deviation (Root Mean Square (RMS) exceeds the value of 60 nm, then the silicon substrate thus obtained covered with a layer of zinc oxide is applied to gold, by the PVD (Physical Vapor Deposition) method. Furthermore, the invention includes the platform thus obtained.
