Abstract: The present invention provides a surface plasmon-optical-electrical hybrid conduction nano heterostructure and a preparation method therefor. The structure includes an exciting light source, a semiconductor nano-structure array, a two-dimensional plasmonic micro-nano structure, a sub-wavelength plasmon polariton guided wave, an emergent optical wave, a one-dimensional plasmonic micro-nano structure, a wire, a metal electrode, a conductive substrate, a probe molecule, an atomic-force microscopic conductive probe and a voltage source. The method achieves a semiconductor seed crystal with controllable distribution and density by controlling free metal ions, air, water or oxygen on a metal substrate to achieve highly uniform control of the seed crystal, and then strictly controls a length-to-diameter ratio and distribution of a semiconductor structure by continuous growth. Therefore, a new nano optics platform is provided for studying various novel effects produced by interaction between light and substances.
