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.

09 Nov 2009 | Papers | 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...
Notes on Scattering and Mobility in 1D, 2D, and 3D
06 Nov 2009 | Teaching Materials | Contributor(s): Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) or
quantum confined (2D and 1D) semiconductor structures. Analytical estimates are made
that show the mobility in...

5.0 out of 5 stars
02 Sep 2008 | Online Presentations | Contributor(s): Dragica Vasileska, Stephen M. Goodnick
This presentation illustrates several points. First, it is shown that in nanoscale devices there is less degradation due to heating effects due to non-stationary nature of the carrier transport...
