The discovery of the hydrogen-rich superconductor H3S with a Tc of about 200 K has ignited interest in room-temperature superconductivity, but understanding the superconducting pairing mechanism is limited. While the macroscopic properties of hydrides are well-characterized, determining the superconducting gap under high pressure presents significant challenges. Traditional techniques like angle-resolved photoemission spectroscopy are ineffective in such conditions. Innovative approaches like infrared reflectance spectroscopy have been attempted, but results are hindered by complexities in high-pressure environments. A precise understanding of the superconducting gap is essential for validating theoretical computations and advancing the field of superconductivity in hydrides.
The search for room-temperature superconductivity in hydrogen-rich compounds intensifies after the discovery of H3S, but understanding the superconducting mechanism remains elusive.
While hydrides showcase superconducting properties, such as electrical resistance and magnetization, there's limited experimental insight into the underlying superconducting pairing mechanism.
High-pressure conditions pose challenges for conventional techniques in determining superconducting parameters, demonstrating the need for innovative methods like infrared reflectance spectroscopy.
Determining the superconducting gap size and symmetry is critical to validate theoretical predictions and enable advancements in room-temperature superconductivity research.
