Abstract

Metal assisted chemical etching in combination with nanosphere lithography is a low cost fabrication method to produce Si nanopillars (SiNPLs) with controlled size, periodicity and high aspect ratio in a large scale. These SiNPLs show a refractive index gradient condition from top to bottom of the SiNPLs due to the presence of inhomogeneous mesoporous structures Here, for the first time we report the Omnidirectional and polarization
