Evidence for Virtual Phonon Exchange Between 2-D Electron Gases
This paper reviews our study of the interaction of phonons with two-dimensional electron gases (2DEG) using a direct probe of electron-electron (e-e) scattering rates. We find evidence for an e-e scattering pr...

Compressibility of the Interacting Two-Dimensional Electron Gas
A new technique has been employed to study the compressibility of the two-dimensional electron gas. This technique, based upon a double-layer 2D system, is typically 100 times more sensitive than the tradition...

The Fractional Quantum Hall Effect at Even Denominators
The recent discovery of the fractional quantum Hall effect (FQHE) at the even—denominator filling fraction v=5/2 represents yet another surprise in the area of two-dimensional electron physics. Previous to the wo...
