We have used radio-frequency (rf) reflectometry for sensitive, large bandwidth measurements of two-dimensional (2D) systems in AlGaAs/GaAs heterostructures at millikelvin temperatures. We show that the sample geometry is important in explaining the r

Ultra-sensitive detectors and readout devices based on the radio frequency single electron transistor (rf-SET) combine near quantum-limited sensitivity with fast operation. Here we describe a twin rf-SET detector that uses two superconducting rf-SETs

The radio frequency single electron transistor (rf-SET) is a prime candidate for reading out the final state of a qubit in a solid state quantum computer. Such a measurement requires the detection of sub-electron charge motion in the presence of rand

Towards the ultimate goal of reading out a solid state quantum computer, we have developed a twin radio frequency single electron transistor (rf-SET) device that is capable of cross-correlated measurements of sub-electron charges on microsecond time-

Cyclotron resonance in undoped, top-gated heterostructures

Autor: Roger A Lewis, R. G. Clark, N. E. Lumpkin, Loren Pfeiffer, Dwight G. Rickel, R. J. Heron, Ken W. West, R. P. Starrett, Bruce E. Kane, G. R. Facer

We report on cyclotron resonance detected by far-infrared photoconductivity of the two-dimensional electron gas formed in undoped, top-gated GaAs/Al0.3Ga0.7As heterostructures. The photoconductivity method demonstrated here is readily extendable to q

The B-T phase diagram for thin film YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} with B parallel to the superconducting layers has been constructed from GHz transport measurements to 150 T. Up to 110 T the upper critical field is found to be linear in T and i

We consider the magnetoresistance oscillation phenomena in the Bechgaard salts (TMTSF)(2)X, where X = ClO4, PF6, and AsF6 in pulsed magnetic fields to 51 T. Of particular importance is the observation of a new magnetoresistance oscillation for X = Cl

Central-cell corrections for Si and S in GaAs in a strong magnetic field

The central-cell correction has been determined experimentally for the two donor impurities S and Si in GaAs. Data have been obtained for magnetic fields to 39 T, corresponding to γ≈6. The observed behavior is in good agreement with theory. The an
