Synthesis of Silicon and Silicon Carbide Nanoparticles by Pulsed Electrical Discharges in Dielectric Liquids

Combustion Synthesis of Silicon Carbide

Combustion synthesis (CS) is an effective technique to produce a wide variety of advanced materials that include powders and net shape products of ceramics, intermetallics, composites and functionally graded materials. This method was discovered in the beginning of 1970's in the former Soviet Union (Merzhanov & Borovinskaya, 1972), and the development of this technique has led to the appearance...

Electrical Characterization of Microelectromechanical Silicon Carbide Resonators

This manuscript describes the findings of a study to investigate the performance of SiC MEMS resonators with respect to resonant frequency and quality factor under a variety of testing conditions, including various ambient pressures, AC drive voltages, bias potentials and temperatures. The sample set included both single-crystal and polycrystalline 3C-SiC lateral resonators. The experimental re...

Silicon Nitride and Silicon Carbide

Synthesis and characterization of silicon carbide, silicon oxynitride and silicon nitride nanowires

Several methods have been employed to synthesize SiC nanowires. The methods include heating silica gel or fumed silica with activated carbon in a reducing atmosphere, the carbon particles being produced in situ in one of the methods. The simplest method to obtain b-SiC nanowires involves heating silica gel with activated carbon at 1360 uC in H2 or NH3. The same reaction, if carried out in the p...

Optimization of Non-volatile Memory Cell and Energy Consumption in Robot Systems by Synthesized Silicon Nanoparticles via Electrical Discharge

In this paper, we propose to optimize manufacturing methods of memory cells by produced silicon nanoparticles via electrical spark discharge of silicon electrodes in water to reduce the energy consumption for low power applications. The pulsed spark discharge with the peak current of 60 A and a duration of a single discharge pulse of 60 µs was used in our experiment. The structure, morphology, ...
