Description

In physics, a phonon is a quasiparticle characterized by the quantization of the modes of lattice vibrations of periodic, elastic crystal structures of solids. The study of phonons is an important part of solid state physics because phonons play a major role in many of the physical properties of solids, including a material's thermal and electrical conductivities.

    Papers | 31 Jan 2022 | Contributor(s):: Timothy S Fisher

    These lecture notes provide a detailed treatment of the thermal energy storage and transport by conduction in natural and fabricated structures.

  2. Scattering in NEGF: Made simple

    Papers | 09 Nov 2009 | Contributor(s):: Dmitri Nikonov, Himadri Pal, George Bourianoff

    Formalism for describing electron-phonon scattering, surface scattering, and spin relaxation is dervied for the Keldysh non-equilibrium Green's functions (NEGF) method. Approximation useful for efficient numerical solution are described. The specific case of the nanoMOS simulator is...
