Organometallic-Inorganic Hybrid MXenes with Tunable Superconductivity
16 Feb 2025
Abstract
Ti-based two-dimensional transition-metal carbides (MXenes) have attracted
attention due to their superior properties and are being explored across
various applications1,2. Despite their versatile properties, superconductivity
has never been demonstrated, not even predicted, for this important group of 2D
materials. In this work, we have introduced an electrochemical intercalation
protocol to construct versatile organometallic-inorganic hybrid MXenes and
achieved tunable superconductivity in the metallocene-modified layered
crystals. Through structural editing of MXene matrix at atomic scale and
meticulously modulated intercalation route, Ti3C2Tx intercalated with
metallocene species exhibits a superconductive transition temperature (Tc) of
10.2 K. Guest intercalation induced electron filling and strain engineering are
responsible for the emerging superconductivity in this intrinsically
non-superconducting material. Theoretically, simulated electron-phonon
interaction effects further elucidate the nature of the changes in Tc.
Furthermore, the Tc of crafted artificial superlattices beyond Ti-based MXenes
have been predicted, offering a general strategy for engineering
superconductivity and magnetism in layered hybrid materials.
