Measurements\nfrom the infrared to the ultraviolet reveal significant changes in the optical\nconductivity of graphene for both electron and hole doping. The shift,\nbroadening, and modification in shape of the saddle-point exciton resonance\nreflect strong screening of the many-body interactions by...
Many-body van der Waals interactions in multilayer structures studied by atomic force microscopy Many-body van-der-Waals interaction in multilayer structures has long been predicted but is difficult to be observed experimentally. Here the authors verify it in a tip graphene-substrate system benefiting...
years in the application of carbon-based nanomaterials such as charcoal, graphite, fullerene, single-wall carbon nanotubes (SWCNTs), multi-wall carbon nanotubes (MWCNTs), and graphene. This is due to the exploitation of their unique properties, such as enhanced electrical, thermal, mechanical, and...
Grapheneis a 2Dnanomaterialmade of sp2-hybridized carbon atoms arranged in a honeycomb lattice. Graphene has unique electronic, electrical, thermal, mechanical, andoptical properties[1]. Considering the exceptional properties of graphene and its derivatives, they are explored in the fields of batteries...
Graphene materials can deplete essential micronutrients from cell culture media and potentially interfere with probe dyes used during in vitro analysis of cell viability and function by (1) adsorbing dyes before they can interact with their target biomolecule, (2) quenching fluorescence after the intera...
However, thus far, the influence of many-body interactions on the CR of bilayer graphene (BLG) has been rarely studied, even though BLG also possesses nonparabolic band dispersion. Here, we investigate CR in the h-BN/BLG/h-BN structure via magneto-photothermoelectric measurements under infrared...
Graphene is the core supporting material for the wearable technology in the future. Because of its ultra high carrier mobility and flexibility, it is suitable for many smart wearable devices. The diversity of the production of graphene materials allows it to be integrated into wearable devices in ...
These investigations have also indicated the reduced side effects of the drugs used to cure a cancer tumour in the body. However, there are still certain drawbacks associated with the use of nanoparticles. These include agglomeration owing to their high specific surface area and dipole–dipole ...
They have found that cells in the lab grow better on graphene than other materials, and behave more like cells do in the body. "In your body, you don't see many surfaces acting like plastic or glass," said Alex Savchenko, a research scientist at the University of California San Diego ...
We consider the AB-(Bernal) stacking for the bi-layer graphene (BLG) system and assume that a perpendicular electric field is created by the external gates deposited on the BLG surface. In the basis (A1, B2, A2, B1) for the valleyKand the basis (B2, A1,
