Topological Effects in Super-Mossian Nanoparticle Arrays

High refractive index materials have applications in nanophotonics due to their low material losses and ability to confine light at the nanoscale. Moss rule sets an upper limit on the refractive index that can possibly be realized. In this work, a super-Mossian dielectric, iron pyrite FeS
2
, is chosen for observing lattice effects in an array of FeS
2
nanoparticles and analyzing the influence of the lattice topology.
