Study of the indirect interaction in the quantum dots of the graphene bilayer in the framework of the s-d model

Abstract

Specific features of the RKKY interaction in triangular quantum dots of the graphene bilayer have been studied according to the s-d exchange model. Theoretical model calculations showed that, with allowance for an electron spectrum limited by the Dirac approximation, the dependence of the exchange interaction energy on the distance between spins ceases to possess a periodic (oscillatory) character.
