Li Intercalation in MoS2: In Situ Observation of Its Dynamics and Tuning Optical and Electrical Properties.
Two-dimensional layered materials like MoS2 have shown promise for nanoelectronics and energy storage, both as monolayers and as bulk van der Waals crystals with tunable properties. Here we present a platform to tune the physical and chemical properties of nanoscale MoS2 by electrochemically inserting a foreign species (Li(+) ions) into their interlayer spacing. We discover substantial enhancem...
متن کاملIntercalation of few-layer graphite flakes with FeCl3: Raman determination of Fermi level, layer by layer decoupling, and stability.
We use anhydrous ferric chloride (FeCl(3)) to intercalate graphite flakes consisting of 2-4 graphene layers and to dope graphene monolayers. The intercalant, staging, stability, and doping of the resulting intercalation compounds (ICs) are characterized by Raman scattering. The G peak of heavily doped monolayer graphene upshifts to ∼1627 cm(-1). The 2-4 layer ICs have similar upshifts, and a Lo...
متن کاملLi absorption and intercalation in single layer graphene and few layer graphene by first principles.
We present an exhaustive first-principles investigation of Li absorption and intercalation in single layer graphene and few layer graphene, as compared to bulk graphite. For single layer graphene, the cluster expansion method is used to systemically search for the lowest energy ionic configuration as a function of absorbed Li content. It is predicted that there exists no Li arrangement that sta...

در محیط های دانشگاهی ایران ، آموزش ترجمه واژگان هم آیند که به منزله امری لاینفک برای دانش جویان رشته مترجمی زبان می باشد، تا حدود زیادی نادیده گرفته شده است . این واقعیت باعث شده است تا دانش جویان رشته مترجمی زبان در ترجمه ی واژگان هم آیند اشتباهات بسیاری مرتکب شوند. این پژوهش توجه ویژه ای به ترجمه واژگان هم آیند داشته است. برای مشخص نمودن مشکلات و استراتژی های مورد استفاده ی دانش جویان در ترجم...
15 صفحه اولNovel near-infrared emission from crystal defects in MoS2 multilayer flakes
The structural defects in two-dimensional transition metal dichalcogenides, including point defects, dislocations and grain boundaries, are scarcely considered regarding their potential to manipulate the electrical and optical properties of this class of materials, notwithstanding the significant advances already made. Indeed, impurities and vacancies may influence the exciton population, creat...
