Abstract

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.

吸附大分子对单层石墨烯中载流子迁移率的影响：悬挂键模型

AbstractWithin the framework of the previously proposed model (S.Yu. Davydov.Davydov.Phys. Solid State 64, 2018 (2022)）的框架下，研究了大分子（MM）与单层石墨烯（SLG）之间的相互作用是通过悬挂的 MM 键与碳原子的缝合来实现的，研究了这些缝合对石墨烯中载流子迁移率的影响。研究表明，MM-SLG 拼接的短程散射比库仑散射占优势。研究还发现，与短程散射相比，缝合石墨烯变形对迁移率的影响可以忽略不计。研究考虑了自由石墨烯和外延石墨烯的情况。讨论了如何将 MM-SLG 衬底结构用作生物传感器的基础。
