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…
A Finite-field Approach for Calculations Beyond the Random Phase Approximation
He Ma, Marco Govoni, Francois Gygi +1
We describe a finite-field approach to compute density response functions, which allows for efficient and calculations beyond the random phase approximation. T…
Fundamental Principles for Calculating Charged Defect Ionization Energies in Ultrathin Two-Dimensional Materials
Tyler J. Smart, Feng Wu, Marco Govoni +1
Defects in 2D materials are becoming prominent candidates for quantum emitters and scalable optoelectronic applications. However, several physical properties that characterize thei…
Dielectric properties of condensed systems composed of fragments
Ding Pan, Marco Govoni, Giulia Galli
The dielectric properties of molecules or nanostructures are usually modified in a complex manner, when assembled into a condensed phase. We propose a first-principles method to co…
