New Material Combines Two Electric Properties at Once

Topic: Materials Science

Scientists have discovered a material that can be both polar and antiferroelectric. This means it has two properties that were thought to be mutually exclusive. The researchers found this by studying the compound K₃[Nb₃O₆|(BO₃)₂].

Many electronic devices rely on special materials called polar materials. These materials have an uneven distribution of electric charge, making them positive and negative even without an external electric field.

Polar materials are divided into two main groups: ferroelectric and antiferroelectric materials. Ferroelectric materials can change their polarization when an electric field is applied. Antiferroelectric materials, on the other hand, have a unique arrangement of tiny electric dipoles that cancel each other out, making them non-polar.

Researchers believed that antiferroelectric materials could not also be polar. However, a team led by Ivan Ushakov and Dennis Meier has found a material that challenges this idea. They discovered that the compound K₃[Nb₃O₆|(BO₃)₂] can exhibit both ferroelectricity and antiferroelectricity.

This is possible because of a slight tilt in the arrangement of electric dipoles, which allows the material to retain its antiferroelectric properties. The researchers also found that this material has unique 'hybrid' properties when examined under advanced microscopy.
