Boltzmann model for the lattice thermal conductivity in semiconductor nanowires -

Thebian, Dina Merhej (2017)

In this thesis, we have developed a theoretical model to predict the thermal conductivity for cylindrical and pristine nanowires. Boltzmann equation is solved including spatial dependence of the phonon distribution function ...
Enhancing the efficiency of silicon based solar cells by confining photon and phonon in low dimensional structures -

El Helou, Youssef (2017)

The interaction between phonons and photons, in ZnO NWs deposited on a silicon substrate and in silicon resonators arrays, is investigated by means of Raman spectroscopy. The Raman spectra from the ZnO NWs deposited on a ...
Interpolation between linearized and atomistic models for accurate calculation of the lattice thermal conductivity in the full temperature range -

Abou Khalil, Ali Mohammad, (2013)

In this thesis, we developed a model for the lattice thermal conductivity (κ). For the calculation of κ for a single crystal over a full temperature range, the model uses the full Callaway's solution to Boltzmann equation ...
Model for lattice thermal conductivity of clamped and free surface cylindrical nanowires.

Abou Hamdan, Loubnan Fouad (2019)

A model for the prediction of thermal conductivities of cylindrical nanowires (NWs) is presented. The model is based on the solution of the Boltzmann equation within the relaxation time approximation. Silicon (Si) NWs with ...
Modeling the phonon heat transport in semiconductor superlattices -

Harajli, Zeinab Hassan (2016)

Understanding the laws that govern the phonon heat transport at atomic interfaces in crystalline superlattices has long been viewed as a key step toward efficient thermal-management strategy for high-performance ...
Tuning surface phonon polaritons -

Karakachian, Hrag Rafi (2017)

The growing need for the development of nanophotonic devices implies new challenges in describing and manipulating optical and thermal properties in sub- diffraction length scales. Low- loss Surface Phonon Polariton (SPhP) ...
