Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | . Nanostructured silicon layers (3–60 nm) have been formed upon substrates of
monocrystalline silicon with a very large area (100 cm2
), multicrystalline and
metallurgical silicon by stain etching. We studied optical and structural properties of
nanostructured silicon using scanning tunnel microscopy, scanning electron microscopy,
Auger electron spectroscopy, secondary ion mass spectrometry, and photoluminescence
methods. Results of studying the nanostructured Si properties obtained using the method
of chemical processing have confirmed an opportunity to create this multifunctional
material with stable characteristics. The authors have developed the sensor systems with
use of nanostructured silicon as a sensitive layer, which properties depend on thickness
of the obtained layer and are controlled by parameters of the respective technological
process. Using the example of the photoluminescent sensor with the nanostructured Si
layer, it has been shown that such a sensor can be successfully used to detect small
concentrations of toxins (pesticides phosalone 10⁻⁸ - 10⁻⁹ mol/l ) as well as for specific
biological pollutants, such as protein components, polysaccharides, cells worsening the
quality of products of biotechnological synthesis. |
