Электронно-энергетические и оптические характреристики двухслойных графен-графеновых, графен-боронитридных и боронитрид-боронитридных структур, допированных атомами лития

Abstract

Computational scheme, based on density functional theory, adapted for systems with translational symmetry with exchange-correlation potential of gradient type in a biexponential valence orbitals basis was applied to the research of electron-energy and the optical characteristics of bilayer structures on the basic of graphene and hexagonal boron nitride, both the «pristine» and doped with lithium atoms. Dependence on the lithium atoms concentration of a chemical potential level position and an energy gain, accompanied the lithium atoms implementation process into the corresponding interplanar region of two-dimensional structures was analyzed.

Вычислительная схема, базирующаяся на теории функционала плотности, адаптированная для систем с трансляционной симметрией с обменно-кореляционным потенциалом градиентного типа в базисе двухэкспонентных валентных орбиталей применена к изучению электронно-энергетических и оптических характеристик двухслойных структур на основе графена и гексагонального нитрида бора, как «чистых», так и допированных атомами лития. Проанализирована зависимость от концентрации атомов лития положения уровней химического потенциала и энергетических выигрышей, сопровождаемых процесс внедрения атомов лития в соответствующие межплоскостные области двумерных структур.
