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

Technological 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 pi-conjugated polymers. It also discusses how the new classes of organic spintronics can bridge these performance gaps. Semiconductors and superconductors may not meet the increasing demand for safe yet efficient applications in this quantum age. High-performing organic spintronics utilizing ionic liquids (ILs), liquid and soft crystals, and open shell macroradicals can offer safer, faster, low-power computing and extended spin-relaxation times. This perspective delves into these challenges and explores the potential of this emerging spintronics class to resolve performance issuesimage.
