It has recently been realized that ferroic domain walls constitute a new group of 2D functional nanomaterials. With diverse properties, innate mobility and the capability to be spontaneously created or destroyed, the potential role for domain walls in novel devices is obvious. This discussion meeting will consider the latest research on domain wall properties and their use in future applications. This is a residential conference, which allows for increased discussion and networking. It is free to attend, however participants need to cover their accommodation and catering costs if required. Poster submissions are welcome for this meeting.
