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.

  19. Is dual gate device structure better from a thermal perspective?

    01 Sep 2008 | | 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 (velocity overshoot) in the device, which, in turn, makes less probable the interaction with phonons....
