We investigate the localization of charged particles by the image potential of spherical shells, such as fullerene buckyballs. These spherical image states exist within surface potentials formed by the competition between the attractive image potential and the repulsive centripetal force arising from the angular motion. The image potential has a power law rather than a logarithmic behavior. This leads to fundamental differences in the nature of the effective potential for the two geometries. Our calculations have shown that the captured charge is more strongly localized closest to the surface for fullerenes than for cylindrical nanotube.
我们通过诸如富勒烯巴基球等球壳的镜像势来研究带电粒子的局域化。这些球形镜像态存在于由吸引性镜像势与角向运动产生的排斥性向心力之间的竞争所形成的表面势中。镜像势具有幂律而非对数行为。这导致了两种几何形状的有效势在性质上的根本差异。我们的计算表明，对于富勒烯而言，被俘获的电荷比圆柱形纳米管更强烈地局域在最靠近表面的位置。
