“…The presence of Si nanocrystals can explain the broad PL signal in the visible spectral range. Indeed, as shown in refs and , Si nanostructures with high surface-to-volume ratio (e.g., Si nanocrystals with diameter lower than 8 nm) demonstrate photoluminescence in the visible spectral range because of quantum-sized effects.…”

A micro- or nanosized electrically controlled source of optical radiation is one of the key elements in optoelectronic systems. The phenomenon of light emission via inelastic tunneling (LEIT) of electrons through potential barriers or junctions opens up new possibilities for development of such sources. In this work, we present a simple approach for fabrication of nanoscale electrically driven light sources based on LEIT. We employ STM lithography to locally modify the surface of a Si/Au film stack via heating, which is enabled by a high-density tunnel current. Using the proposed technique, hybrid Si/Au nanoantennas with a minimum diameter of 60 nm were formed. Studying both electronic and optical properties of the obtained nanoantennas, we confirm that the resulting structures can efficiently emit photons in the visible range because of inelastic scattering of electrons. The proposed approach allows for fabrication of nanosized hybrid nanoantennas and studying their properties using STM.

“…The experimental setup for producing silicon-based nanoparticles using the laser-induced pyrolysis of gases was described previously [18,19]. The decomposition reaction of the gas mixture containing highly purified monosilane SiH 4 , boron trichloride BCl 3 and helium is performed in a flow reactor under the irradiation of a CO 2 laser ILGN-802 with a radiation wavelength of 10.6 μm, an output power of 70 W and a beam diameter of 6 mm.…”

In this work the synthesis and physical properties of composite Si-B nanoparticles are described. Boron-silicon-containing nanoparticles were obtained with the laser-induced pyrolysis of a silane and boron trichloride mixture under cw CO 2 -laser irradiation. The particles are heterogeneous in their composition structure: particles consisting of both the crystalline and amorphous phases. The size of the crystalline silicon phase depends on the gas flows' ratio and at the equal point P(SiH 4 ):P(BCl 3 ) = 1:1 the crystalline core has almost disappeared. The possible pyrolysis reaction mechanism was proposed on the basis of the FTIR and TEM data.
