Method for making optical spring based on single polar semiconductor nano-strip

Abstract

The invention discloses a method for manufacturing an optical spring based on individual polar semiconductor nanometer band, including the following steps: 1) a semiconductor powder is adopted as the material to prepare a floccule of semiconductor nanometer band; 2) volatile solution is used as dispersing liquid to dissolve the floccule of semiconductor nanometer band in the dispersing agent, then the floccule of the semiconductor nanometer band is dispersed into individual polar semiconductor nanometer band suspending in the dispersing fluid after being vibrated by the ultrasound; 3) a monocrystalline silicon piece which forms a silicon dioxide insulating layer in the air is adopted as a substrate; 4) the dispersing liquid with suspending individual polar semiconductor nanometer band is dropped on the substrate and an individual nanometer band with random distribution is obtained after the natural volatilization; 5) the nanometer probe technology is used for selecting the individual polar semiconductor nanometer band of a flat substrate which has the maximum spontaneous polarization and piezoelectric effect along the vertical direction as the optical spring based on the individual polar semiconductor nanometer band. The invention has the advantages that: the optical spring based on the individual II-IV family semiconductor piezoelectricity nanometer band has large flexible photoinduced and the photoinduced strain capacity can reach 2%; the optical spring has high positioning accuracy, is suitable for the technical requirement of the micro / nano-electron mechanical system and belongs to the field of high and new technology.
