For practical use, the roughness of the surface was improved by deposited a Si3N4 thin film with 5000 ?. Then their optical and roughness properties were characterized by FTIR and AFM, respectively. As a result of the synergetic effects rendered by heat isolation and high reflection properties, the array of the one-dimensional porous silicon photonic crystal exhibit feasibility as the substrate for pyroelectric infrared sensor. 参考文献 相似文献 引证文献
