There is a fascinating paper this week in Nature Physics about chaotic behaviour that has been spotted in a ferroelectric material. It’s an unexpected discovery that the researchers claim could lead to the development of computers that resemble the human brain.
The story begins with Anton Ievlev and colleagues at Oak Ridge National Lab in the US using the tip of a scanning probe microscope (SPM) to draw patterns on the surface of a ferroelectric material. Ferroelectrics have a spontaneous electric polarization, the direction of which can be reversed by applying an electric field.
