发布日期：2023年07月16日 分类：物理学
常温超导是指在常规气温条件下（通常指接近或低于室温），材料能够以零电阻电流的形式传导电能。根据当前的科学知识与技术发展，目前尚未发现能在常温下实现超导的材料。
超导材料的主要特征是其在低温下（通常接近绝对零度或接近液氮温度）能够展现出零电阻与完全排斥磁场的性质。这些材料包括铜氧化物和铁基超导体等。然而，要在常温下实现超导需要克服许多严峻的挑战。
常温超导的主要挑战之一是温度。传统的超导材料需要极低的温度来实现超导态，因为在较高温度下，热能会破坏超导电子对的配对。此外，超导材料的制备方法和结构也对其超导温度起着重要的影响。
科学家正在积极探索新的材料和机制，以解决常温超导的难题。例如，高温超导材料中铜氧化物的研究引起了广泛的关注，因为它们展现出更高的临界温度。此外，研究人员还在探索其他材料和压力调控等方法，以寻求实现常温超导的突破。
尽管常温超导目前还没有被实现，但科学界对此仍然抱有希望。随着科技的不断进步和新的发现，也许将来我们能够找到更适合于常温超导的材料以及更好的制备方法，从而实现这一目标。

Is room-temperature superconductivity possible?
Room temperature superconductivity refers to the phenomenon where materials can conduct electrical energy in the form of zero-resistance current under normal temperature conditions (typically near or below room temperature). Based on current scientific knowledge and technological developments, materials that can achieve superconductivity at room temperature have not been discovered yet.
The main characteristic of superconducting materials is their ability to exhibit zero resistance and complete expulsion of magnetic fields at low temperatures (usually close to absolute zero or near liquid nitrogen temperature). These materials include copper oxides and iron-based superconductors, among others. However, achieving superconductivity at room temperature requires overcoming many significant challenges.
One of the main challenges of room temperature superconductivity is temperature. Traditional superconducting materials require extremely low temperatures to achieve a superconducting state because thermal energy disrupts the pairing of superconducting electron pairs at higher temperatures. Additionally, the preparation methods and structure of superconducting materials also have a significant impact on their superconducting temperature.
Scientists are actively exploring new materials and mechanisms to address the challenges of room temperature superconductivity. For example, research on copper oxide in high-temperature superconducting materials has attracted widespread attention due to their higher critical temperatures. Furthermore, researchers are also exploring other materials and methods such as pressure tuning to seek breakthroughs in achieving room temperature superconductivity.
Although room temperature superconductivity has not been achieved yet, the scientific community remains hopeful. With continuous technological advancements and new discoveries, it is possible that in the future, we may find materials better suited for room temperature superconductivity and improved preparation methods to achieve this goal.
