Study challenges ideas about piezoelectricity in ferroelectric crystals

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

2D material twist may lead to improved electronic, optical devices
