Evidence of Direct Electronic Band Gap in two-dimensional van der Waals Indium Selenide crystals
Hugo Henck, Debora Pierucci, Jihene Zribi +12
Metal mono-chalcogenide compounds offer a large variety of electronic properties depending on chemical composition, number of layers and stacking-order. Among them, the InSe has at…
Ultrafast electrons dynamics reveal the high potential of InSe for hot carrier optoelectronics
Zhesheng Chen, Christine Giorgetti, Jelena Sjakste +9
We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxat…
Exciton band structure in two-dimensional materials
Pierluigi Cudazzo, Lorenzo Sponza, Christine Giorgetti +3
Low-dimensional materials differ from their bulk counterpart in many respects. In particular, the screening of the Coulomb interaction is strongly reduced, which can have important…
Excitons and stacking order in h-BN
Romain Bourrellier, Michele Amato, Luiz Henrique Galvão Tizei +8
The strong excitonic emission at 5.75 eV of hexagonal boron nitride (h-BN) makes this material one of the most promising candidate for light emitting devices in the far ultraviolet…
Anomalous Angular Dependence of the Dynamic Structure Factor near Bragg Reflections: Graphite
R. Hambach, C. Giorgetti, N. Hiraoka +5
The electron energy-loss function of graphite is studied for momentum transfers q beyond the first Brillouin zone. We find that near Bragg reflections the spectra can change drasti…
Ab initio GW many-body effects in graphene
P. E. Trevisanutto, C. Giorgetti, L. Reining +2
We present an {\it ab initio} many-body GW calculation of the self-energy, the quasiparticle band plot and the spectral functions in free-standing undoped graphene. With respect to…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
Rare earth contributions to the X-ray magnetic circular dichroism at the Co K edge in rare earth-cobalt compounds investigated by multiple-scattering calculations
J. P. Rueff, R. M. Galera, Ch. Giorgetti +3
The X-ray magnetic circular dichroism (XMCD) has been measured at the Co K edge in Co-hcp and R-Co compounds (R=La, Tb, Dy). The structure of the experimental XMCD spectra in the n…
