Resistance standard using quantization of the Hall resistance of GaAs-Al<i>x</i>Ga1−<i>x</i>As heterostructures

Quantization of the Hall resistance of the two-dimensional electron gas in GaAs-AlxGa1−xAs heterostructures is observed at 4.2 K and at magnetic fields as low as 4.2 T. This dem...

g-Factor enhancement in the 2D electron gas in GaAs/AlGaAs heterojunctions

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...

Far infrared resonant magnetoabsorption in low density Si inversion layers

High field magnetoconductivity of Si inversion layers

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...
