HTS

Definition

HTS, or High-Temperature Superconductors, are materials that exhibit superconductivity at temperatures significantly higher than traditional superconductors, often above 77 Kelvin. This ability to operate at elevated temperatures makes HTS attractive for various applications, especially in energy-efficient technologies like generators and motors.
