Topological materials are a class of materials that have unique properties arising from their electronic structure and the way their atoms are arranged. These materials can exhibit special behaviors, such as conducting electricity on their surfaces while remaining insulating in their bulk, due to their topological characteristics. This makes them interesting for applications in electronics and quantum computing. Researchers study topological materials to understand their potential for new technologies. Notable examples include topological insulators and topological superconductors, which have garnered attention for their ability to host exotic particles like Majorana fermions. These materials could lead to advancements in robust quantum computing and energy-efficient devices.
