A new family of BiS₂-type chalcogenide materials for optoelectronics and water splitting applications

In this talk I will show a set of layered materials discovered and studied by means of first-principles calculations. They belong to the family of BiS₂, which has a ‘wrong’ stoichiometry, implying a low-symmetry layered unit cell. In the bulk, several members of this family are promising as photocatalysts for the water splitting reaction. However, their monolayer exhibits a large exciton binding energy, which could be useful for optoelectronic applications, such as light harvesting.
