Magnetic properties of β12-borophene in the presence of electric field and dilute charged impurity

Abstract

Abstract Monoatomic lattice of boron atoms (borophene), a new low-dimensional material shows promising physical and chemical properties. Recently, on the most stable borophene, metal β 12 -borophene, electronic phase transition from metal-to-semimetal and metal-to-semiconductor in the presence of perpendicular electric field and dilute charged impurity is found, respectively. From this point, in this paper, we study the magnetic properties of the electric field and charged impurity induced β 12 -borophene. Particularly, we have calculated Pauli spin paramagnetic susceptibility (PSPS) quantity using the five-band tight-binding Hamiltonian and the Green’s function approach for different interaction-dependent models. The charged impurity and perpendicular electric field effects on the susceptibility of β 12 -borophene show that the “pristine” PSPS of inversion symmetric model in β 12 -borophene is larger than the homogeneous model as well as the Dirac fermions contribute to the total PSPS more than triplet fermions. Further, we found out that the dilute charged impurity does not influence PSPS of the principle system significantly at all temperatures and it decreases slightly with impurity concentration and scattering potential. On the other hand, electric field-induced PSPS results in an increasing (decreasing) trend for PSPS at very low (intermediate and high) temperatures. Our findings pave the way for the industrial practical applications.
