Strong phase correlation between diffusons governs heat conduction in amorphous silicon
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Understanding the thermal vibrations and thermal transport in amorphous materials is an important but long-standing issue in several theoretical and practical fields. Using direct…
Quantum mechanical modeling of anharmonic phonon-phonon scattering in nanostructures
Yangyu Guo, Marc Bescond, Zhongwei Zhang +3
The coherent quantum effect becomes increasingly important in the heat dissipation bottleneck of semiconductor nanoelectronics with the characteristic size shrinking down to few na…
Self-synchronization of thermal phonons at equilibrium
Zhongwei Zhang, Yangyu Guo, Marc Bescond +3
Self-synchronization is a ubiquitous phenomenon in nature, in which oscillators are collectively locked in frequency and phase through mutual interactions. While self-synchronizati…
Impact of electron-phonon scattering on optical properties of CHNHPbI hybrid perovskite material
Benoit Galvani, Daniel Suchet, Amaury Delamarre +5
We investigate numerically the impact of the electron-phonon scattering on the optical properties of a perovskite material (CH3NH3PbI3). Using non-equilibrium Green functions forma…
Beneficial impact of tunneling in nano-structured intermediate-band solar cell
Nicolas Cavassilas, Daniel Suchet, Amaury Delamarre +5
Using the non equilibrium Green functions formalism we propose a study of the electronic excitation and collection in nano-structured intermediate-band solar cell. We demonstrate t…
Improvement of current-control induced by oxide crenel in very short field-effect-transistor
Nicolas Cavassilas, Marc Bescond, Jean-Luc Autran
A 2D quantum ballistic transport model based on the non-equilibrium Green's function formalism has been used to theoretically investigate the effects induced by an oxide crenel in…
