Abstract

Two-dimensional (2D) halide organic-inorganic perovskites (HOIPs) are emerging materials offering synthesis growth versatility and remarkable properties to be explored due to the tunability of their crystal structure. The present research proposal intends to use different 2D HOIPs as the matrix to enclose metal complex magnets for magnetoelectric coupling. By introducing spin degree of freedom in these 2D structures, one can envisage the application in optoelectronic associated to spintronics and making possible electrical controlling on magnetic devices. Therefore, the central aim of this proposal is to synthesize 2D perovskite crystals with building blocks of n layers of [MX6]4 octahedral sheets as multiple-quantum-wells sandwiched by two layers of metal complex acting as barrier spacer and providing magnetism. In other words, the perovskite inorganic layer can provide semiconducting properties while metal complexes introduce magnetic properties. The significance of this research project is apparent in both fundamental knowledge of magnetic-electric coupling and the need for technological innovation in quantum information. The induction of magnetoelectric coupling in these nanostructured 2D hybrid materials can be very important for technological application and can yield high-impact results in interdisciplinary fields (physic, chemistry, materials science, and engineering). In addition, a better understanding of the intriguing physical properties due to interaction between magnetism in the organic layer and quantum well confinement effect of the electrical charges in the inorganic layer can be obtained.
