Electrons can now be controlled to build smarter quantum devices

Auburn University scientists have developed a novel class of materials called Surface Immobilized Electrides, which enable precise control over free electrons within matter. Unlike typical materials where electrons remain bound to atoms, these electrides allow electrons to move freely through stable surfaces such as diamond and silicon carbide. By manipulating the molecular arrangement, electrons can form isolated “islands” functioning as quantum bits or spread into metallic “seas” that enhance chemical reactions. This breakthrough offers a versatile platform with potential applications in quantum computing, catalysis, and advanced manufacturing. The innovation addresses previous challenges with electrides, which were unstable and difficult to reproduce, by depositing the materials directly onto solid surfaces to improve stability and scalability. This advancement could lead to commercial uses in electronics, sensors, and catalysts, bridging fundamental science and practical technology. The interdisciplinary research team highlights that controlling free electrons opens new avenues for faster computers, smarter machines, and more efficient industrial processes, marking a significant step toward future quantum technologies and clean manufacturing solutions.
