Silicon Nanowire Industry Uses & Growth

PVI’s Graphene Production System provides to solar cells, batteries / electronics and solar fuel generators. Chemical Vapor Deposition system for large-area vapor-liquid-solid catalyzed silicon microwire growth. This computer-controlled system is equipped for up to 6” wafer capacity.

Silicon Microwire Technology Using Chemical Vapor Deposition

High fatality, wafer-scale silicon microwire arrays by vapor-liquid-solid (VLS) growth

High electronic quality with well-controlled doping densities. (>>30 um carrier diffusion length. <<50 cm s-1 surface recombination velocity. 6 orders of magnitude tunability of doping concentration.) Full tunability of wire architectures and optical properties. Cheap precursors and atmospheric growth process for technology scale-up. Re-use of the Si substrates with versatile wire transfer process onto flexible polymer films.
