We explore how material selection affects the electromagnetic response of closely positioned asymmetric nanostructures. COMSOL Multiphysics is used to model the system, and the materials studied include gold (Au), gallium arsenide (GaAs), indium tin oxide (ITO), and aluminum zinc oxide (AZO). All materials produce average electric field magnitudes on the order of 10 MV/m. We conclude that the ITO and AZO nanostructures produce the most uniform electric field response over the entire domain of incident wavelengths and that GaAs is least thermally stable in a vacuum environment due to its low heat conductivity.

用于粒子处理的非对称半导体纳米结构

我们探索材料选择如何影响紧密定位的不对称纳米结构的电磁响应。COMSOL Multiphysics用于对系统进行建模，所研究的材料包括金（Au），砷化镓（GaAs），氧化铟锡（ITO）和氧化铝锌（AZO）。所有材料产生的平均电场强度约为10 MV / m。我们得出的结论是，ITO和AZO纳米结构在整个入射波长范围内产生最均匀的电场响应，并且由于其低导热性，GaAs在真空环境中的热稳定性最低。
