Determination of the phonon sidebands in the photoluminescence spectrum of semiconductor nanoclusters from ab initio calculations
Peng Han, Gabriel Bester
We propose a theoretical approach based on (constrained) density functional theory and the Franck-Condon approximation for the calculation of the temperature dependent photolumines…
Frozen-phonon method for state anticrossing situations and its application to zero-point motion effects in diamondoids
Pablo García-Risueño, Peng Han, Gabriel Bester
The frozen-phonon method, used to calculate electron-phonon coupling effects, requires calculations of the investigated structure using atomic coordinates displaced according to a…
Phonon-assisted Auger enables ultrafast charge transfer in CdSe Quantum Dot/Organic Molecule
Zhi Wang, Mona Rafipoor, Pablo García Risueño +4
Charge transfer between photoexcited quantum dots and molecular acceptors is one of the key limiting processes in most applications of colloidal nanostructures, most prominently in…
Heavy strain conditions in colloidal core-shell quantum dots and their consequences on the vibrational properties from \emph{Ab initio} calculations
Peng Han, Gabriel Bester
We preform large-scale \emph{ab initio} density functional theory calculations to study the lattice strain and the vibrational properties of colloidal semiconductor core-shell nano…
Vibron-vibron coupling from ab initio molecular dynamics simulations of a silicon cluster
Peng Han, Linas Vilciauskas, Gabriel Bester
We study the temperature dependent dynamical processes of a Si10H16 cluster and obtain a blue shift of the Si-Si vibrational modes with transverse acoustic character and a red shif…
Strong terahertz emission from superlattices via Zener tunneling
Peng Han, Kui-juan Jin, Barry C. Sanders +3
We develop a comprehensive, elegant theory to explain terahertz (THz) emission from a superlattice over a wide range of applied electric field,which shows excellent agreement betwe…
