Defects in nanostructures have been considered as limitations for electron-based information transmission. Quasiparticles like plasmons, phonons, and spins serve as potential alternatives to electrons, yet their stabilization requires the creation of spatially strongly correlated defects within nanostructures, a challenging task within inorganic lattices. Here, we target to utilize organic nano lattices as an alternative for quasiparticle stabilization. Our focus is on investigating the defect distribution and packing structure of 2D colloidal nanoparticles, under varying conditions of temperature, packing density, and pair-wised interaction using molecular dynamics simulations. In our model, we treat metal-loaded block copolymers as hard-core soft-shell colloidal systems. To understand the defect distribution under the melting process, we employ a range of analysis techniques, including bond-orientational function, structure factor, positional correlation function and defect density counting.
