Abstract: Abstract The nonpolar a-plane p-AlxGa1-xN/GaN superlattices (SLs) were successfully grown with metal organic chemical vapor deposition technology. The surface morphology, carrier concentration, layer thickness, and Al composition for the nonpolar a-plane p-AlxGa1-xN/GaN SLs were characterized… read more here.

Abstract: AlxGa1–xN/GaN disk-in-wire polar nanostructures were fabricated, and their optical properties were studied. Wavelength tuning was observed by locally controlling the strain in each nanopillar via its diameter. The measured wavelength shift was in an excellent… read more here.
