: We show that electric field imprinting technique allows for patterning of metal nanoparticles in the glass matrix at the subwavelength scale. The formation of glass-metal nanocomposite strips with a width down to 150 nm is demonstrated. The results of near-field microscopy of imprinted patterns are in good agreement with the performed numerical modeling. Atomic force microscopy reveals that imprinting also results in the formation of nanoscale surface profile with the height going down with the decrease of the strip width. The experiments prove the applicability of this technique for the fabrication of nanoscale plasmonic components.
我们表明，电场压印技术可在亚波长尺度上对玻璃基质中的金属纳米颗粒进行图案化。证明了宽度低至 150nm 的玻璃-金属纳米复合条带的形成。压印图案的近场显微镜结果与所进行的数值模拟吻合良好。原子力显微镜显示，压印还导致纳米级表面轮廓的形成，其高度随条带宽度的减小而降低。实验证明了该技术在纳米级等离子体组件制造中的适用性。
