| titleOfInvention | Artificial microstructure with longitudinally-graded plasmon enhanced infrared wide-spectrum absorption |
| abstract | The invention discloses an artificial microstructure for enhancing wide infrared spectrum absorption by plasmon polariton with longitudinal gradual change. The key point is that the light trapping structure is combined with plasmon polariton, a periodic columnar structure is formed on the surface of a mercury cadmium telluride sample through micro-nano processing, and then a gold film is deposited on the surface of the microstructure. The gold film at the bevel of the prism after deposition has different transverse and longitudinal thicknesses (transverse thickness is much smaller than longitudinal thickness) due to the gradient of the prism sides. Under the time-varying electric field, plasmon polaritons generated by the gold thin layers on the surfaces of the prisms and plasmon polaritons adjacent to the prisms resonate to generate a transverse propagation mode. The surface microstructure designed in the patent has smaller geometric dimension than that of the surface microstructure of the traditional light trapping structure, can further reduce intrinsic dark current caused by the volume of the material, simultaneously keeps high quantum efficiency and improves the performance of the device. |
