An early research investigation to explore a two-dimensional electron gas with respect to cyclotron resonance behavior and the de Haas van Alphen effect.
32.
These materials can be modeled reasonably well by the free electron gas theory assuming a parabolic conduction band and doping levels above the Mott Criterion.
33.
:: I don't think a gas has to be composed of atoms-see photon gas, Bose gas, electron gas.
34.
For metals, the electron gas's Fermi temperature is generally many thousands of kelvins, so in human applications they can be considered degenerate.
35.
A measurement on a free electron gas for example would give a positive intensity for momenta p and zero intensity for p > p _ F.
36.
Thus at high densities, when r _ s, the effect of the Coulomb interaction is weak and the free electron gas is a good approximation.
37.
When a positive voltage greater than the threshold voltage is applied to the gate, electrons accumulate at the interface and form a two-dimensional electron gas.
38.
Exotic examples of degenerate matter include conduction electrons alone as a degenerate, free electron gas while the majority of the electrons are regarded as occupying bound quantum states.
39.
As in the Drude model, valence electrons are assumed to be completely detached from their ions ( forming an "'electron gas "').
40.
The resulting dielectric function, also called the " Lindhard dielectric function ", correctly predicts a number of properties of the electron gas, including plasmons.
