Carrier relaxation with LO phonon decay in semiconductor quantum dots.
, 2001 Anal. of an exactly sol. model of phonons coupled to a carrier in a quantum dot provides a clear illustration of a phonon bottleneck to relaxation. The introduction of three-phonon interactions leads to a broad window for relaxation by the processes of ...

Giant Angular Nernst Effect in the Organic Metal α-(BEDT-TTF)2KHg(SCN)4
Magnetochemistry, 2023 We have detected a large Nernst effect in the charge density wave state of the multiband organic metal α-(BEDT-TTF)2KHg(SCN)4. We find that apart from the phonon drag effect, the energy relaxation processes that govern the electron–phonon interactions ...

First-principles study of the thermal transport properties of superconducting NbN [PDF]
E3S Web of Conferences, 2023 We investigate the thermal transport properties of NbN by considering three-phonon scattering (3ph), four-phonon scattering (4ph), electron-phonon (ep) scattering, and isotope (iso) scattering.

Circumventing the phonon bottleneck by multiphonon-mediated hot exciton cooling at the nanoscale
npj Computational Materials, 2023 Nonradiative processes govern efficiencies of semiconductor nanocrystal (NC)-based devices. A central process is hot exciton cooling, or the nonradiative relaxation of a highly excited electron/hole pair to form a band-edge exciton.

Modeling of Polarization-Specific Phonon Transmission Through Interfaces [PDF]
, 2011 In this work, the atomistic Green\u27s function method is extended to compute transmission functions for each phonon polarization. The eigenvectors and eigenvalues of the overall density of states matrices are manipulated to yield a density of states ...

Probing bath-induced entanglement in a qubit pair by measuring photon correlations [PDF]
, 2014 Self-assembled quantum dots (QDs) are ideal structures in which to test theories of open quantum systems: confined exciton states can be coherently manipulated and their decoherence properties are dominated by interactions with acoustic phonons.

Efficient phonon cascades in WSe2 monolayers
Nature Communications, 2021 The primary stages of carrier relaxation in atomically thin transition metal dichalcogenides are hardly accessible due to their fast timescales. Here, the authors measure the first stages of carrier–phonon interaction in monolayer WSe2 via a series of ...

Bosonic spectral function and the electron-phonon interaction in HTSC cuprates [PDF]
, 2010 In this paper we discuss experimental evidence related to the structure and origin of the bosonic spectral function alpha 2F (omega) in high-temperature superconducting (HTSC) cuprates at and near optimal doping.
