Thermoresponsive photonic crystals
Webb27 feb. 2012 · The sol‐gel route leads to hematite with a photonic crystal structure (PC‐ α ‐Fe 2 O 3) being faithfully replicated from a biotemplate, and the desired magnetophotonic crystal Fe 3 O 4 (MPC‐Fe 3 O 4) is obtained by the reduction of the PC‐ α ‐Fe 2 O 3 under a H 2 /Ar atmosphere. WebbThe inventor of photonic crystals himself, Eli Yablonovitch, came up with the idea of photonic crystals while investigating the conditions of light trapping within the photodetector active area. He was analyzing ways to push the detector quantum efficiency closer to the fundamental performance limits, also known as the conventional limit, the …
