Abstract

The invention discloses a glass surface nanofabrication method based on friction-induced selective etching, which is mainly applied in the processing of the glass surface micro-nanostructure. The specific operation method comprises the following steps of: installing a probe of which the tip is spherical on an atomic force microscope, fixing the cleaned glass on a sample stage, starting the atomic force microscope, applying a constant load F or a variable load F' on the probe, using the probe to scan on the glass surface along a set scanning track according to the cycle number N and the scanning speed v; and after scanning, placing the glass in an HF solution of which mass concentration is 10-20%, and finally corroding for 5-10 seconds. The method does not require a template or mask, three-dimensional nano-patterns such as slopes, steps and arrays are processed on the glass surface through one-time corrosion; and the processing flow is extremely simple, the corrosion rate is extremely high, and the glass surface nanofabrication method is simple, accurate and efficient.
