Photoconductive gain in semiconductor quantum wires (2008)
Rossler, C., Manus, S., Kotthaus, J. P., Holleitner, A. W., Schuh, D., ...
We report on a photoconductive gain in semiconductor quantum wires which are lithographically defined in an AlGaAs/GaAs quantum well via a shallow-etch technique. The effect allows resolving the...
Dynamic photoconductive gain effect in shallow-etched AlGaAs/GaAs quantum wires (2008)
Rossler, C., Manus, S., Kotthaus, J. P., Holleitner, A. W., Schuh, D., ...
We report on a dynamic photoconductive gain effect in quantum wires which are lithographically fabricated in an AlGaAs/GaAs quantum well via a shallow-etch technique. The effect allows resolving the...
Optically induced transport properties of freely suspended semiconductor submicron channels (2008)
Rossler, C., Manus, S., Ludwig, S., Kotthaus, J. P., Simon, J., ...
We report on optically induced transport phenomena in freely suspended channels containing a two-dimensional electron gas (2DEG). The submicron devices are fabricated in AlGaAs/GaAs heterostructures...
LARGE CAPACITY LASER MEMORY FOR SPACEBORNE COMPUTERS. (2005)
The report discusses the necessity for a spaceborne computer memory of at least 10 to the 7th power bit capacity. It is shown that such a device could minimize computer hardware and, at the same...
Shayegan, M., Karrai, K., Shkolnikov, Y. P., Vakili, K., De Poortere, E. P., Manus, S.
We demonstrate the use of a piezoelectric actuator to apply, at low temperatures, uniaxial stress in the plane of a two-dimensional electron system confined to a modulation-doped AlAs quantum well....
Nanomechanical resonators operating as charge detectors in the nonlinear regime (1999)
Kroemmer, H., Erbe, A., Tilke, A., Manus, S., Blick, R. H.
We present measurements on nanomechanical resonators machined from Silicon-on-Insulator substrates. The resonators are designed as freely suspended Au/Si beams of lengths on the order of 1 - 4 um and...
Parallel Quantum-Point-Contacts as High-Frequency-Mixers (1997)
Haubrich, A. G. C., Wharam, D. A., Kriegelstein, H., Manus, S., Lorke, A., Gossard, A. C., ...
We present the results of high-frequency mixing experiments performed upon parallel quantum point-contacts defined in the two-dimensional electron gas of an Al_{x}Ga_{1-x}As/GaAs-heterostructure. The...
