## Description

- description: Kagome metals AV 3Sb 5 (A = K, Rb, Cs) are renowned for their intricate
    electronic band structures, providing a rich platform for investigating topological
    states and electronic correlations. Within the AV 3Sb 5 family, the detailed electronic
    structures of CsV 3Sb 5 and KV 3Sb 5 have been well established, both in their
    charge-density-wave (CDW) phase or in the pristine metallic phase. Yet, the electronic
    structure of RbV 3Sb 5 remains under-explored. In this manuscript, we present
    a detailed study of the electronic structure of RbV 3Sb 5 revealed by Shubnikov–de
    Haas oscillation in both the CDW phase (9 kbar), and where the CDW phase is just
    fully suppressed (22 kbar). The greatly simplified Fast Fourier transform spectrum
    at 22 kbar implies the absence of Fermi surface reconstruction caused by the CDW
    order, and the observation of enhanced quasi-particle effective masses near the
    CDW boundary indicates enhanced quantum fluctuations. Furthermore, the mobilities
    of charge carriers from the CDW phase to the metallic pristine phase are studied
    using mobility spectrum analysis (MSA). Our MSA results reveal that high-mobility
    carriers (≈10,000 cm  2/Vs) coexist with the non-monotonic Hall effect near-zero
    field at 9 kbar. As the pressure increases to 22 kbar and 30 kbar, this non-monotonic
    feature is suppressed, concomitant with the disappearance of the high-mobility
    carriers. By summarizing the MSA results across the AV 3Sb 5 family, we observed
    that the superconducting behavior appears to be positively correlated with carrier
    mobility and number. This correlation suggests that high-mobility carriers may
    play a crucial role in the underlying superconducting pairing mechanism.
