When heat goes astray -- non-local heating in a semiconductor
Mahmoud Elhajhasan, Elena Trukhan, Katharina Dudde +8
Heating of semiconductor devices limits their performance and lifetime, which must be addressed by thermal management starting at the heat source. It is a common assumption that th…
Interband and kinetic corrections to the electronic Boltzmann transport equation
Elena Trukhan, Nakib H. Protik
Interband effects such as coherence/tunneling have recently been shown to give an important contribution to the charge and heat transport properties under certain conditions. These…
Ab initio study of Coulomb drag driven electron-hole bifluidity in doped graphene
Dwaipayan Paul, Elena Trukhan, Nakib H. Protik
Motivated by the notion that a preponderance of Coulomb interactions might lead to hydrodynamics, we carry out an ab initio calculation of the charge carrier transport properties o…
Phonon Mean Free Path Spectroscopy By Raman Thermometry
Katharina Dudde, Mahmoud Elhajhasan, Guillaume Würsch +6
In this work, we exemplify on a bulk silicon sample that Raman thermometry is capable of phonon mean free path (PMFP) spectroscopy. Our experimental approach is similar to the vari…
Thermal analysis of GaN-based photonic membranes for optoelectronics
Wilken Seemann, Mahmoud Elhajhasan, Julian Themann +11
Semiconductor membranes find their widespread use in various research fields targeting medical, biological, environmental, and optical applications. Often such membranes derive the…
Beyond the Tamura model of phonon-isotope scattering
Nakib H. Protik, Claudia Draxl
The Tamura model is a particular type of 1 Born approximation of the phonon-isotope scattering problem. The expression for the mode-resolved phonon-isotope scattering…
