piezoresponse force microscopy (PFM)
Piezoresponse Force Microscopy (PFM) is a sophisticated imaging technique used to study the electrical properties of materials at the nanoscale. It works by applying a voltage through a tiny probe that touches the material's surface, causing it to deform slightly due to its piezoelectric properties—where electrical signals lead to mechanical changes. PFM maps these responses, providing detailed information about the material's behavior and characteristics, which is valuable in fields like materials science, electronics, and sensor technology. Essentially, it helps scientists visualize and understand how materials respond to electric fields at a very small scale.

Piezoresponse Force Microscopy (PFM) is a specialized technique used to study materials that change shape or produce electric signals when stressed, known as piezoelectric materials. In PFM, a tiny probe touches the surface of a sample, applying an electric voltage that induces mechanical changes. By measuring these responses, researchers can visualize and understand the material's properties at the nanoscale. PFM is valuable in fields like materials science and nanotechnology, helping to develop advanced technologies such as sensors and energy harvesters.
