Ion Beam Nanostructuring of HgCdTe Ternary Compound.

Systematic study of mercury cadmium telluride thin films subjected to the ion beam bombardment was carried out. The evolution of surface morphology of (111) Hg Cd Te (x ~ 0.223) epilayers due to 100 keV B and Ag ion irradiation was studied by AFM and SEM methods.

Silicon Substrate Strained and Structured via Cavitation Effect for Photovoltaic and Biomedical Application.

A hybrid structure, which integrates the nanostructured silicon with a bio-active silicate, is fabricated using the method of MHz sonication in the cryogenic environment. Optical, atomic force, and scanning electron microscopy techniques as well as energy dispersive X-ray spectroscopy were used for the investigation of the morphology and chemical compound of the structured surface. Micro-Raman as well as X-ray diffraction, ellipsometry, and photovoltage spectroscopy was used for the obtained structures characterization.
