摘要
在先前提出的模型框架内(S.Yu。达维多夫。理论物理。Solid State 64, 2018(2022))，其中大分子(MM)与单层石墨烯(SLG)通过拼接悬垂的MM键与碳原子进行相互作用，研究了这些拼接对石墨烯中载流子迁移率的影响。结果表明，MM-SLG拼接的近程散射优于库仑散射。研究还发现，与近程散射相比，拼接石墨烯变形对迁移率的影响可以忽略不计。考虑了自由石墨烯和外延石墨烯的情况。讨论了利用mm - slg衬底结构作为生物传感器的基础。
Влияние адсорбированной макромолекулы на подвижность носителей в однослойном графене: модель оборванных связей
Within the framework of the previously proposed model (S.Yu. Davydov. Phys. Solid State 64, 2018 (2022)), in which the interaction of a macromolecule (MM) with single-layer graphene (SLG) is carried out by stitching of dangling MM bonds with carbon atoms, the effect of these stitching on the mobility of carriers in graphene was studied. It is shown that short-range scattering of MM-SLG stitching prevails over Coulomb scattering. It has also been found that the effect of induced by stitching graphene deformation on mobility can be neglected compared to short-range scattering. The cases of free and epitaxial graphene are considered. The use of the MM-SLG-substrate structure as the basis of a biosensor is discussed.
