FIG. 1.

(Color online) Calculated band gaps for square lattice arrays of Si NPs, with radius 50 nm and lattice constants (a) 300 nm and (b) 400 nm. (c) FEM model geometry used to simulate the X directed optical transmission spectrum through the lattice. Simulated transmission spectra for the NP arrays with a of (d) 300 nm and (e) 400 nm. (f) TM-mode wave propagation of an 800 nm wave through an empty cell. (g) Propagation of the same in the presence of Si NCs.
