Advances in High-Temperature Superconductors: Mechanisms and Applications in Modern Electronics

Abstract

High-temperature superconductors (HTS) have marked a significant advancement in material science by exhibiting superconductivity at temperatures well above those required for conventional superconductors. This paper explores the mechanisms underlying HTS, including the deviation from traditional Bardeen-Cooper-Schrieffer (BCS) theory and the complex interactions that contribute to their high critical temperatures. Recent discoveries, such as hydrogen-rich materials and novel compounds, are highlighted to showcase the progress in HTS research. The paper also delves into the fabrication techniques used to synthesize HTS materials, including solid-state reaction, chemical vapor deposition, and molecular beam epitaxy, alongside advanced characterization methods like X-ray diffraction and scanning tunneling microscopy. The practical applications of HTS in modern electronics are examined, covering areas such as power transmission, magnetic levitation, high-speed digital circuits, and medical imaging. The promising advancements, challenges such as high costs and fabrication complexity persist. Future directions are proposed, focusing on material innovation, cost reduction, and expanding practical implementations. This comprehensive overview underscores the transformative potential of HTS in revolutionizing technology and addresses the ongoing research needed to overcome existing barriers.
