Domain boundary-dominated systems: adaptive structures and functional twin boundaries
DD Viehland, EKH Salje - Advances in physics, 2014 - Taylor & Francis
Domain boundaries typically constitute only a minute fraction of the total volume of a crystal.
However, a special (but not unusual) situation can occur in which the domain boundary …
