Abstract
The influences of porosity on thermal radiation were studied for enhancement of light absorption in porous silicon (pSi) photonic crystal (PhCs). A 2D concept of unit-cell for square and triangular lattice of circular air holes was formulated and solved using plane wave expansion (PWE) technique and Fourier expansion method. The spectral energy density (SED) of the thermal radiation at different porosity consideration of silicon PhC was investigated for both mentioned lattices including the effect of these lattice structures in the creation of photonic band gaps. It revealed useful to increase the number of frequency band gaps by subjecting the PhC to a square lattice at low porosity. Moreover, a triangular lattice beyond 50% of porosity would be suitable in thermal radiation control where the band gap stabilization applications are required.
