Review on recent trend of solar photovoltaic technology - …

Amorphous silicon is the most commonly developed and a non-crystalline allotropic form of silicon. It is most popular among thin film technology but it is prone to degradation. Some of the varieties of a-Si are amorphous silicon carbide (a-SiC), amorphous silicon germanium (a-SiGe), microcrystalline silicon (μ-Si) and amorphous silicon-nitride (a-SiN) ( Parida et al., 2011 ).

Exposure Data - - NCBI Bookshelf

Silicon carbide appears in two different crystalline forms: hexagonal α-silicon carbide is the main product, while cubic β-silicon carbide is formed at lower temperatures (Føreland et al., 2008). Silicon carbide occurs in several forms: as “non-fibrous,” as “polycrystalline fibres,” or as one of more than 150 different single-crystal modifiions (or polytypes) of “whiskers

Survivability of presolar oxygen isotopic signature of …

This critical survival temperature of presolar amorphous silie grains is lower than that of presolar silicon carbide grains (~1100 K; Mendybaev et al. 2002). Therefore, presolar amorphous silies would have lost their presolar isotopic signatures at 500–1100 K in the protosolar disk within the disk lifetime although presolar silicon carbide grains may have survived in such an environment.
