传统的表面等离激元材料,由于其介电函数虚部不可忽略,在金属与光的相互作用过程中,所造成的吸收损耗是在所难免的。而氮化钛(TiN)虽然是非金属,但是其介电函数与金、银等传统表面等离激元材料相似,并且吸收损耗相对金属较低,从而可以表现出较好的表面等离激元特性。其各种结构在表面等离激元研究领域有潜在的应用前景。 Traditional surface plasmon polaritons, due to their imaginary part of the dielectric function can not be ignored, in the interaction of metal and light absorption loss caused by the inevitable. Although titanium nitride (TiN) is non-metallic, its dielectric function is similar to that of traditional surface plasmon polaritons such as gold and silver, and its absorption loss is relatively low relative to metal, so that it can exhibit better surface plasmon characteristic. Its various structures have potential applications in the field of surface plasmon resonance research.
