摘要

我们从理论上研究了由金属纳米粒子组成的量子等离子体超表面的光学性质，这些金属纳米粒子以亚纳米间隙的二维矩阵形式排列。我们采用一种随时间变化的密度泛函理论方法来计算超表面的光学性质。由于隧穿电流的作用，它们在小于0.4 nm的间隙处表现出特有的特性。

Numerical Analysis of Quantum Plasmonic Metasuraface by Time-Dependent Density Functional Theory

We theoretically investigate optical properties of a quantum plasmonic metasurface composed of metallic nanoparticles that are arranged in a two-dimensional matrix form with a sub-nanometer gap. We employ a time-dependent density functional theory approach to calculate optical properties of the metasurface. They show characteristic features at gap distance smaller than 0.4 nm due to the tunneling currents that flow through the gaps.
