Electronic structure of folded hexagonal boron nitride
Anthony Impellizzeri, Michele Amato, Chris P. Ewels +1
Folded regions are commonly encountered in a number of hexagonal boron nitride (h-BN) based bulk and nanostructured materials. Two types of structural modifications occur in folded…
Interplay of quantum confinement and strain effects in type I to type II transition in Ge/Si core-shell nanocrystals
Ivan Marri, Stefano Ossicini, Michele Amato +2
The electronic properties of hydrogenated, spherical, Si/Ge and Ge/Si core-shell nanocrystals with a diameter ranging from 1.8 to 4.0 nm are studied within Density Functional Theor…
Atomic scale visualization of the p-d hybridization in III-V semiconductors doped with transition metal impurities
K. Badiane, G. Rodary, M. Amato +4
p-d hybridization of transition metal impurities in a semiconductor host is the mechanism that couples valence-band electrons and localized spins. We use scanning tunneling microsc…
Fermi resonance in the Raman spectrum of graphene
Dipankar Kalita, Michele Amato, Alexandre Artaud +6
We report the observation of an intense anomalous peak at 1608 cm in the Raman spectrum of graphene associated to the presence of chromium nanoparticles in contact with grap…
Extrinsic doping in group IV hexagonal-diamond type crystals
Michele Amato, Thanayut Kaewmaraya, Alberto Zobelli
Over the last few years, group IV hexagonal-diamond type crystals have acquired great attention in semiconductor physics thanks to the appearance of novel and very effective growth…
Tuning the Work Function of Si(100) Surface by Halogen Absorption: A DFT Study
Matteo Bertocchi, Michele Amato, Ivan Marri +1
First-principles calculations of work function tuning induced by different chemical terminations on Si(100) surface are presented and discussed. We find that the presence of haloge…
