WebApr 9, 2024 · In this study, an artificial neural network that can predict the band structure of 2-D photonic crystals is developed. Three kinds of photonic crystals in a square lattice, triangular lattice, and honeycomb lattice and two kinds of materials with different refractive indices are investigated. WebAug 29, 2024 · The crystals are irradiated by 4.5 MeV oxygen ions at a fluence of 5 × 10 14 ions/cm 2 and 1.5 × 10 15 ions/cm 2 at room temperature. The oxygen ion’s beam is scanned to ensure uniform irradiation with current of 100 nA, and beam direction is tilted by 7° to prevent channeling effects.
