Pseudo-spin model of argentophilicity in honeycomb bilayered materials
arXiv:2307.13651 · doi:10.1016/j.mtphys.2023.101271
Abstract
We introduce a pseudo-spin model for the argentophilic bond expected in silver-based bilayered materials arising from a spontaneous pseudo-magnetic field interacting with pseudo-spins of two unconventional Ag ions, namely and electronically distinct from (albeit energetically degenerate to) the conventional cation typically observed in monolayered materials. This model suggests the possibility of tuning the dimensionality and hence the conductor-semiconductor-insulator properties of honeycomb bilayered materials by application of external fields, analogous to driving a superconducting or Coulomb blockade system to the normal regime by critical magnetic or electric fields respectively.
