Abstract

Optimization of growth parameters has permitted to create monolithic nanocomposites with buried nanocrystals (NCs) of iron and chromium disilicides and polycrystalline nanocomposites with buried Mg₂Si NCs (3-40 nm) on the base of reactive deposition epitaxy (RDE), solid phase epitaxy(SPE) and molecular beam epitaxy (MBE), which demonstrated wonderful thermoelectrical properties and the possibility of strong light emission with wavelength of 1.2 - 1.6 microns in the mesa-diode structures with p-n junction at direct and back bias. Doping process of Mg₂Si nanocrystals inside nanocomposite layers was developed on the base of ordered surface phases of metals on a silicon substrate. Nanocomposite layers with n- and p-type conductivity have been successfully grown. The huge increase of Zeebeck coefficient in the Si-p/β-FeSi₂ NCs/Si-p and Si/Mg₂Si NCs/Si nanocomposites has been found.
