Abstract
Monolayer β12-borophene hosts two different Dirac and triplet fermions. Due to the large number of atoms in its unit cell, a description of their perturbed models leads to interesting phenomena. In this paper, we focus on an analytical tight-binding framework to describe the effect of adsorbed gas molecules on the magnetic properties of β12-borophene. We employ the Green’s function approach to calculate the Pauli spin paramagnetic susceptibility of the system. With this, we explain the peculiar characteristics of magnetic responses of the system depending on the position of gas molecules on the host boron atoms. From a wider perspective, these results can be useful for practical applications based on low-dimensional gas sensors.
