Bridging Performance Gaps: Exploring New Classes of Materials for Future Spintronics Technological Challenges

Abstract

AbstractTechnological challenges, such as insufficient computation power, inefficient data storage, and unsafe communication, may not be tackled by currently utilized semiconductors or superconductors, which are still far from meeting the requirements of quantum‐age applications. Spintronics, focused on electron transport phenomena dependent on spin, holds promise as an advanced technology. Nevertheless, most recent quantum technologies adopted by leading businesses and start‐ups rely heavily on others, and there is a race to increase the number of qubits to gain a computational advantage. Therefore, it is crucial to consider new classes of materials instead of the conventional ones. Developing high‐performance organic spintronics based on new classes of materials, namely, ionic liquids (ILs), liquid and soft crystals, and macroradicals, can support high‐speed and low‐power computing applications, offering higher spin‐relaxation times in the order of microsecond at room temperature. This perspective discusses the key challenges of the currently utilized inorganic semiconductors, small molecules, and π‐conjugated polymers. It also discusses how the new classes of organic spintronics can bridge these performance gaps.
