Coexistence of extended flat band and Kekulé order in Li-intercalated graphene

چکیده
Doping graphene near the 1/4 filling to shift extended flat band and van Hove singularity below E$_F$ has been highly desirable. Here we report experimental observation of an in Li-intercalated graphene. Strong electron-phonon interaction is clearly identified by notable kinks dispersion. Moreover, evolution structure upon Li intercalation shows that Kekul\'e order emerge simultaneously. Our work provides opportunities for investigating related instabilities its interplay with

Flat-band ferromagnetism in armchair graphene nanoribbons
We study the electronic correlation effects in armchair graphene nanoribbons that have been recently proposed to be the building blocks of spin qubits. The armchair edges give rise to peculiar quantum interferences and lead to quenched kinetic energy of the itinerant carriers at appropriate doping level. This is a beautiful one-dimensional analogy of the Landaulevel formation in two dimensions ...
متن کاملNanoscale 3-D (E, kx, ky) band structure imaging on graphene and intercalated graphene
An x-ray photoemission electron microscope (X-PEEM) equipped with a hemispherical energy analyzer is capable of fast acquisition of momentum-resolved photoelectron angular distribution patterns in a complete cone. We have applied this technique to observe the 3-D ðE; kx; kyÞ electronic band structure of zero-, one-, and two-monolayer (ML) graphene grown ex situ on 6H-SiC(0001) substrates where ...

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولCoexistence of Buckled and Flat Monolayers
The minimum surface tension and respreadability of a surfactant monolayer is limited by a two to three dimensional instability called collapse. Liquid-condensed or solid phase monolayers collapse via fracture followed by loss of material. Liquid-expanded phase monolayers collapse by solubilization into the subphase. Monolayers that retain a continuous liquid-expanded phase network surrounding i...
