All-dielectric nanophotonics based on high-index dielectric nanoparticles became a powerful platform for modern light science, providing many fascinating applications, including high-efficient nanoantennas and metamaterials. High-index dielectric nanostructures are of a special interest for nonlinear nanophotonics, where they demonstrate special types of optical nonlinearity, such as electron-hole...
Amorphous silicon (a-Si:H) thin-films being an advantageous base for solar cells manufacturing face several disadvantages, such as relatively wide bandgap (1.7… 1.8 eV) and cells degradation effect during prolonged sun exposure (Staebler-Wronski Effect) that lowers the efficiency of the cells compared to, for instance, monocrystalline solar cells. We suggest enhancing the solar cell conversion efficiency...
The CdS/CNT composite is of particular interest in many application fields, since it was shown that it is capable of generating photocurrent from visible light with unusually high efficiency and for microwave reduction properties. But there is a little information about the electronic properties. In this paper we focus on improving electrical properties by deposition CdS nanoparticles on CNTs. The...
We reported a surface charge sensitive suspended nanoparticle crystal (S-NPC) as a promising nanofluidic-based sensing strategy. In the S-NPC, interspaces among nanoparticles construct a nanochannel network and provide nanofluidic electrokinetic properties. When electric double layers inside the interspaces are overlapped, conductance across the S-NPC will be directly related to the surface charge...
A technique was reported on controlled synthesis of Au and Au/Ag nanoparticles using thermal (500°C) annealing of Au thin film and Ag/Au bilayer. The density of the nanoparticles can be adjusted in a range of 2.8×109 cm-2 to 6.2×1010 cm-2. The nanoparticles were used as masks for fabrications of vertically aligned amorphous Si nanowires (a-SiNWs) using dry etching. The mechanisms on the density control...
Extreme small-gap lithography is necessary for future bit-patterned media, but is under-explored due to lack of etch masks with small enough gaps. Self-assembled nanoparticle arrays featuring 2 nm gaps are promising candidates, but exhibit lateral instability during etching. We present a novel one-step method for stabilizing their order by exposing to intense electron beam doses, and show pattern...
The effective removal of nano particles from silicon wafer surface was demonstrated using the self-channeled plasma filament excited by a femtosecond (130 fs) Ti:Sapphire laser (lambdap=790 nm). This process has achieved successfully the removal of 100 nm sized polystyrene latex (PSL) particles from the surface. The photoinduced self-channeled plasma filament in air reached a length of approximately...
Nanostructuring is one of the effective approaches to lower the thermal conductivity of materials. Nanostructured skutterudite-related compounds CoSb3, Fe0.5Ni0.5Sb3, Fe0.25Ni0.25Co0.5Sb3 and Te-doped CoSb3 were synthesized by a solvothermal route. The bulk materials were prepared by hot pressing or spark plasma sintering from the solvothermally synthesized nanopowders. The thermal conductivity values...
