Excitonic states and structural stability in two-dimensional hybrid organic-inorganic perovskites

Two-dimensional (2D) perovskites are a new class of functional materials that may find applications in various technologically important areas. Due to the better moisture and illumination stability, layered perovskites can be the next generation of materials for solar light-harvesting applications,...
