Study challenges ideas about piezoelectricity in ferroelectric crystals

Penn State researchers found the idea that smaller domains lead to higher piezoelectricity is based on very limited existing data without a solid theoretical foundation.

The two types of interfaces between layers of transition metal dichalcogenides (TMD) 2D materials where the top layer is a Janus TMD with two types of atoms (selenium and sulfur) and the bottom layer is a regular TMD with one type of atom (sulfur). The S/S interface is much stronger than the Se/S interface due to the charge distribution from the imbalance in S atoms. Courtesy: Penn State Materials Research Institute
