By controlling the arrangement of multiple inorganic and organic layers within crystals using a novel technique, researchers at Duke University and Purdue University have shown they can control the energy levels of electrons and holes (positive charge carriers) within a class of materials called perovskites. This tuning influences the materials' optoelectronic properties and their ability to emit light of specific energies, demonstrated by their ability to function as a source of lasers.

One important foundation of the computational work is a long-standing investment into the creation of computational simulation codes for materials properties.

Perovskite materials are a class of compounds that have gained significant attention in the field of materials science due to their unique properties, particularly in the area of semiconductors. These materials, which are defined by their specific crystalline structure, can be used in applications likeThe paper focuses on refining the structural control of layered perovskite materials with organic semiconductor incorporation.
