Evidence for a Collective Ground State in Si Inversion Layers in the Extreme Quantum Limit

Infrared measurements of the cyclotron resonance in the two-dimensional electron gas reveal a remarkable line narrowing and shift if and only if the lowest Landau level is parti...

Observation of the Two-Dimensional Plasmon in Silicon Inversion Layers

The two-dimensional plasmon of an $n$ inversion layer of (100) $p$-type Si is observed at a fixed wave vector as a function of electron density. The position, width, and strengt...

Frequency Dependence of the Electron Conductivity in the Silicon Inversion Layer in the Metallic and Localized Regimes

The conductivity of electrons in the inversion layer of silicon has been measured from 0 to 40 ${\mathrm{cm}}^{\ensuremath{-}1}$ at 1.2\ifmmode^\circ\else\textdegree\fi{}K in th...

Far-Infrared Cyclotron Resonance in the Inversion Layer of Silicon

Cyclotron resonance in the $n$-type inversion layer of silicon has been observed at 4.2\ifmmode^\circ\else\textdegree\fi{}K for electron densities between (0.38 and 9.0) \ifmmod...
