Аннотация: Self-organized α-FeSi2 nanocrystals on (100) silicon substrate were synthesized by molecular beam epitaxy with Au catalyst. The microstructure and basic orientation relationship between the silicide nanocrystals and silicon substrate were analyzed in detail. α-FeSi2 nanocrystals appeared to be inclined trapezoid and rectangular nanoplates, polyhedral nanobars and pyramid-like ones, aligned along 011 directions on (100) silicon substrate with the length up to 1.5 μm, width ranging between 80 and 500 nm and thickness from 30 to 170 nm. As has been proposed metallic iron silicide may be used for manufacturing electric contacts on silicon. A current-voltage characteristic of the structure was measured at room temperature and showed good linearity.

Аннотация: The rough surface of nano-crystalline diamond spheres induces surface electronic states which appear as a broadened pre-peak over approx. 15 eV at the C K-edge energy threshold for carbon in the parallel electron energy loss spectrum (PEELS). This appears to be at least partially due to 1s-pi* transitions, although typically the latter occupy a range of only 4 eV for the sp(2) edge of highly-oriented pyrollytic graphite (HOPG). No pi* electrons appear in the conduction band inside the diamond particles, where all electrons are sp(3) hybridized. PEELS data were also obtained from a chemical vapour deposited diamond film (CVDF) and gem-quality diamond for comparison with the spectra of nano-diamonds. The density of sp(2) and sp(3) states on the surface of diamond nano-crystals is calculated for simple structural models of the diamond balls, including some conjecture about surface structures. The results are used to interpret the sp(2)/sp(3) ratios measured from the PEELS spectra recorded as scans across the particles. Surface roughness at the atomic scale was also examined using high-resolution transmission electron microscopy (HRTEM) and electron nano-diffraction patterns were used to confirm the crystal structures.

Аннотация: Self-assembled growth of α-FeSi2 nanocrystal ensembles on gold-activated and gold-free Si(001) surface by molecular beam epitaxy is reported. The microstructure and basic orientation relationship (OR) between the silicide nanocrystals and silicon substrate were analysed. The study reveals that utilisation of the gold as catalyst regulates the preferable OR of the nanocrystals with silicon and their habitus. It is shown that electron transport from α-FeSi2 phase into p-Si(001) can be tuned by the formation of (001)-or (111)-textured α-FeSi2 nanocrystals ensembles. A current-voltage characteristic of the structures with different preferable epitaxial alignment (α-FeSi2(001)/Si(100) and α-FeSi2(111)/Si(100)) shows good linearity at room temperature. However, it becomes non-linear at different temperatures for different ORs due to different Schottky barrier height governed by a particular epitaxial alignment of the α-FeSi2/p-Si interfaces.
