Two-dimensional electron gases (2DEGs) at oxide interfaces may exhibit unique properties,
including effects from strong electron correlations, extremely high electron densities …

For electrons tunneling between parallel two-dimensional electron systems, conservation of
in-plane momentum produces sharply resonant current-voltage characteristics and provides …

In this review a survey of tunnelling processes between barrier-separated two-dimensional
(2D) systems and systems of different dimensionality is given. Tunnelling between barrier …

We have measured the low-temperature (4.2 K) current-voltage characteristics I (V) of a
GaAs/(AlGa) As double-barrier resonant tunneling diode in which the quantum well is …

We have measured the tunneling between two two-dimensional electron gases at high
magnetic fields B, when the carrier densities of the two electron layers are matched. For …

We use frequency-dependent capacitance-voltage spectroscopy to measure the tunneling
probability into self-assembled InAs quantum dots. Using an in-plane magnetic field of …

It is shown that the electron scattering by static defects and acoustic or optical phonons in
quantum wells subjected to an in-plane magnetic field is asymmetric. The probability of …

We have studied the in-plane magnetoresistance of coupled double-quantum-well
structures, in which each well has a different mobility and where the values of carrier …

Using the techniques of in situ focused ion beam lithography and molecular beam epitaxy
regrowth high quality, patterned back gate, double quantum well devices have been …

We consider a phase-coherent system of two parallel quantum wires that are coupled via a
tunneling barrier of finite length. The usual perturbative treatment of tunneling fails in this …
