The invention introduces a novel, customizable method to create, manipulate, and erase polar topological structures in ferroelectric materials using atomic force microscopy (AFM). Unlike traditional methods, this technique allows for arbitrary scan paths, enabling rapid, automated, and nanoscale-precise control over the generated structures. Potential applications include memory devices, neuromorphic computing, quantum technologies and high-frequency electronic systems, addressing current limitations in stability, scalability, and flexibility of polar ferroelectric structures.

Description

This method leverages AFM with a specialized tip control to generate complex polar structures within ferroelectric materials. By designing arbitrary scan paths, users can customize and control the topologies created with unprecedented precision, allowing for highly stable structures that can be modified or erased on-demand. This technology enables researchers and manufacturers to expand beyond binary storage, creating devices with multi-state capabilities suitable for advanced data storage and computing.
