Angle-tunable intersubband photoabsorption and enhanced photobleaching in twisted bilayer graphene
Eva A. A. Pogna, Xianchong Miao, Driele von Dreifus +7
Van der Waals heterostructures obtained by artificially stacking two-dimensional crystals represent the frontier of material engineering, demonstrating properties superior to those…
Periodic arrays of intercalated atoms in twisted bilayer graphene: an \it{ ab initio} investigation
R. H. Miwa, P. Venezuela, E. Suárez Morell
We have performed an \it {ab initio} investigation of transition metals (TMs = Mo, Ru, Co, and Pt) embedded in twisted bilayer graphene (tBG) layers. Our total energy results revea…
Raman spectroscopy as probe of nanometer-scale strain variations in graphene
Christoph Neumann, Sven Reichardt, Pedro Venezuela +9
Confocal Raman spectroscopy is a versatile, non-invasive investigation tool and a major workhorse for graphene characterization. Here we show that the experimentally observed Raman…
Spin pumping and interlayer exchange coupling through palladium
D. L. R. Santos, P. Venezuela, R. B. Muniz +1
The magnetic behaviour of ultrathin ferromagnetic films deposited on substrates is strongly affected by the properties of the substrate. We investigate the spin pumping rate, inter…
Theory of double-resonant Raman spectra in graphene: intensity and line shape of defect-induced and two-phonon bands
Pedro Venezuela, Michele Lazzeri, Francesco Mauri
We calculate the double resonant (DR) Raman spectrum of graphene, and determine the lines associated to both phonon-defect processes, and two-phonons ones. Phonon and electronic di…
Emergence of local magnetic moments in doped graphene-related materials
P. Venezuela, R. B. Muniz, A. T. Costa +3
Motivated by recent studies reporting the formation of localized magnetic moments in doped graphene, we investigate the energetic cost for spin polarizing isolated impurities embed…
