Layered Bimetal Nanoporous Platforms for SERS Sensing
Yanqiu Zou, Anastasiia Sapunova, Tommaso Giovannini +15
Nanoporous metals are extensively investigated as platforms for applications in plasmonics. They present high surface areas and strong local electric fields that can be tuned at di…
Understanding the irreversible lithium loss in silicon anodes using multi-edge X-ray scattering analysis
Michael A. Hernandez Bertran, Diana Zapata Dominguez, Christopher Berhaut +10
During the first charge-discharge cycle, silicon-based batteries show an important capacity loss because of the formation of the solid electrolyte interphase (SEI) and morphologica…
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…
Many-body perturbation theory calculations using the yambo code
D. Sangalli, A. Ferretti, H. Miranda +17
yambo is an open source project aimed at studying excited state properties of condensed matter systems from first principles using many-body methods. As input, yambo requires groun…
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…
Carrier Multiplication in Silicon Nanocrystals: Theoretical Methodologies and Role of the Passivation
Ivan Marri, Marco Govoni, Stefano Ossicini
Carrier multiplication is a non-radiative recombination mechanism that leads to the generation of two or more electron-hole pairs after absorption of a single photon. By reducing t…
