Novel Approaches to High-Temperature Superconductivity: A Materials Science Perspective

Abstract

High-temperature superconductivity (HTS) remains one of the most fascinating and challenging frontiers in materials science, offering significant promise for a wide range of applications in energy transmission, magnetic levitation, and quantum computing. Over the past few decades, advancements in the discovery of novel superconducting materials have led to the emergence of various classes of HTS materials, such as copper oxide-based (cuprates), iron-based (pnictides), and hydrogen-rich compounds. Despite considerable progress, the mechanism underlying HTS remains poorly understood. This article provides a comprehensive overview of novel approaches in the development of HTS materials, highlighting key strategies such as doping, heterostructure design, and quantum material synthesis. Additionally, the latest insights into the role of lattice vibrations, electron pairing, and topological states in enhancing superconductivity at elevated temperatures are discussed. The goal is to provide a multidisciplinary perspective on the materials design and challenges that need to be addressed to achieve room-temperature superconductivity.
