debye (D) debye (#) Fr.: debye A → After Peter Joseph Wilhelm Debye (1884-1966), Dutch-born American, who made important studies in the conductivity of electricity by salt solutions and in the heat capacity of solids. He received the 1936 Nobel Prize in chemistry for his work on the structure of molecules. |

Debye length derâzâ-ye Debye (#) Fr.: longueur de Debye A characteristic length scale in a → ^{1/2}, where
T is the electron temperature in → _{e}electron-volts
and n is the electron density in cm_{e}^{-3}.
Particles which pass each other at distances smaller than the Debye length interact directly.
Outside the Debye length particle interactions are dominated by collective effects. In typical
laboratory plasmas the Debye length is small compared with the plasma dimension, so that
collective effects are important. |

Debye model model-e Debye (#) Fr.: modèle de Debye An extension of the → R[(4/x^{2})∫
y^{2}/(e - 1)^{y}dy -
x/(e - 1)], integrating from 0 to ^{x}x,
where R is the → gas constant,
k is → Boltzmann's constant,
x = hν_{max}/k, and
y = hν/k. The parameter
T = _{D}hν_{max}/k
is the characteristic → Debye temperature of the
crystal. At low temperatures the specific heat prediction by this model is
in good agreement with observations (→ Debye law),
in contrast to Einstein's model.→ |
