The proposed structure was demonstrated in p-type cubic silicon carbide nanowires fabried using a top down process. The experimental data showed that the nano strain-amplifier can enhance the sensitivity of SiC strain sensors at least 5.4 times larger than that of the conventional structures.
Silicon Nanowires for Solar Thermal Energy Harvesting: …
4/1/2016· Silicon nanowire possesses great potential as the material for renewable energy harvesting and conversion. The significantly reduced spectral reflectivity of silicon nanowire to visible light makes it even more attractive in solar energy appliions.
