Optical properties of crystalline-amorphous core-shell silicon nanowires.

The optical absorption in a nanowire heterostructure consisting of a crystalline silicon core surrounded by a conformal shell of amorphous silicon is studied. We show that they exhibit extremely high absorption of 95% at short wavelengths (λ < 550 nm) and a concomitant very low absorption of down to less than 2% at long wavelengths (λ > 780 nm). These results indicate that our nanowires do not ...

Silicon Carbide Power Device Characterization for HEVs

The emergence of silicon carbide(SiC-) based power semiconductor switches, with their superior features compared with silicon(Si-) based switches, has resulted in substantial improvement in the performance of power electronics converter systems. These systems with SiC power devices have the qualities of being more compact, lighter, and more efficient; thus, they are ideal for high-voltage power...

Mechanical Properties of Amorphous Silicon Carbide

Excellent physical and chemical properties make silicon carbide (SiC) a prominent candidate for a variety of applications, including high-temperature, high-power, and high-frequency and optoelectronic devices, structural component in fusion reactors, cladding material for gas-cooled fission reactors, and an inert matrix for the transmutation of Pu(Katoh, Y. et al., 2007; Snead, L. L. et al., 20...
