论文摘要
我们使用时间依赖性的扰动理论研究了距纳米尺寸金属簇表面距离距离纳米尺寸金属簇表面的距离的可能性。我们揭示了对图像状态激发的电子的波函数位于表面外,并且电流流在球形壳中,其半径是球体半径的几倍。自旋极光已应用于完美的二十面体金属簇li $ _ {13} $,其优化是通过分子动力学模拟来实现的,并通过DFT方法和radialschrödinger方程的溶液获得了频带结构。据我们所知,尽管他们的特征付出了巨大的努力,但图像电子并不是关于光引起电流的研究的主题。
We study the possibility of the generation of the photo-induced image currents at a distance from the surface of nano-sized metal clusters by using time-dependent perturbation theory. We reveal that the wave function of an electron excited to the image state is localized outside the surface and current flows in a spherical shell whose radius is a few times the radius of the sphere. Spin polarized light has been applied to a perfect icosahedral metal cluster Li$_{13}$ whose optimization is achieved by molecular dynamic simulation and band structure is obtained by DFT method and by solution of radial Schrödinger equation. Up to our knowledge, despite the great effort on their characteristics, image electrons have not been the subject of the studies on photo-induced current.
