Dimensionality-driven colossal excitons in semiconducting yttrium carbide (MXene) Link here: https://doi.org/10.1016/j.cartre.2026.100642 Abstract: The recent synthesis of stoichiometric Y2CF2 marks a paradigm shift in the MXene family, offering a pristine, semiconducting alternative to the metallic and surface-disordered variants typically produced via acid etching. Here, we employ state-of-the-art many-body perturbation theory (RPA and GW+BSE) to unravel the quasiparticle…
