Purpose of the development: The structures are promising for the development of radiating, photo- and heat receivers.

Recommended application field: Devices based on the two-dimensional photonic structures macroporous silicon can be used for the needs of environmental monitoring, monitoring in medicine and industry.

Technical characteristic: Two-dimensional macroporous silicon structures were made with a periodic and random arrangement of macropores with a diameter Dp = 1-10 microns, H = depth of 250 microns Concentration Np = (1,5-6)- 106 cm2. Nano-silica coating to 10 nm, 50800 nanometers thick were formed on the surface of the macropore; Nanocoating in silicon carbide had a thickness of 200 nanometers.

Advantages over analogues: Develop different low cost and the ability to manufacture structures with the desired geometry. During the All-Ukrainian contest "Invention-2008" is recognized as the best invention in the field of materials science.
