Ferroelectric materials like barium titanate, a ceramic used in capacitors, are essential to many electronic devices. Typical ferroelectric materials develop features called domain walls with unusual properties -- such as lines of electrical conduction completely different from the surrounding material. These properties are technologically useful but poorly understood. Now scientists have demonstrated the ability of a powerful imaging tool to provide new insight into the mystery of why domain walls behave in their peculiar ways.
