氧化物和氮化物作为光学范围内的替代等离子体材料

Oxides and nitrides as alternative plasmonic materials in the optical range

Gururaj V. Naik, Jongbum Kim, Alexandra Boltasseva

摘要:

作为传统金属的替代品,新的等离子体材料在快速发展的等离子体和超材料领域提供了许多优势。这些优点包括低本征损耗、基于电容器的设计、与标准纳米纤维工艺的兼容性、可调谐性等。透明导电氧化物如Al:ZnO、Ga:ZnO和氧化铟锡(ITO)使得许多高性能超材料器件能够在近红外工作。过渡金属氮化物如TiN或ZrN可以在可见光频率中替代传统金属。在本文中,我们提供了这些新材料的制造和表征的细节,并讨论其适用于一些超材料和等离子体激元应用。

英文摘要:

As alternatives to conventional metals, new plasmonic materials offer many advantages in the rapidly growing fields of plasmonics and metamaterials. These advantages include low intrinsic loss, semiconductor-based design, compatibility with standard nanofabrication processes, tunability, and others. Transparent conducting oxides such as Al:ZnO, Ga:ZnO and indium-tin-oxide (ITO) enable many high-performance metamaterial devices operating in the near-IR. Transition-metal nitrides such as TiN or ZrN can be substitutes for conventional metals in the visible frequencies. In this paper we provide the details of fabrication and characterization of these new materials and discuss their suitability for a number of metamaterial and plasmonic applications.
