Dilute Nitride III-V Superlattices Lattice-Matched to Silicon


Dilute nitrides quaternary alloys of GaP<sub>1-x-y</sub>As<sub>y </sub>N<sub>x</sub> have attracted much attention since they exhibit a direct bandgap and their lattice constant matches the one of silicon for y=4.7x-0.1. These alloys offer interesting perspectives for the monolithic integration of III-V photovoltaics with the silicon technology. However… (More)
