Crystal-orientation dependant spin dephasing for 2D and bulk electrons in GaAs wires (2009)

Denega, S. Z., Last, T., Liu, J., Slachter, A., Rizo, P. J., ...

We report the observation of spin dephasing anisotropy for quasi-1D electron ensembles in wires etched into a GaAs/AlGaAs heterojunction system. Time-resolved Kerr rotation measurements show...

Optical probing of spin dynamics of two-dimensional and bulk electrons in a GaAs/AlGaAs heterojunction system (2009)

Rizo, P. J., Pugzlys, A., Slachter, A., Denega, S. Z., Reuter, D., Wieck, A. D., ...

We present time-resolved Kerr rotation measurements of electron spin dynamics in a GaAs/AlGaAs heterojunction system that contains a high-mobility two-dimensional electron gas (2DEG). Due to the...

Compact cryogenic Kerr microscope for time-resolved studies of electron spin transport in microstructures (2008)

Rizo, P. J., Pugžlys, A., Liu, J., Reuter, D., Wieck, A. D., Van Der Wal, C. H., ...

A compact cryogenic Kerr microscope for operation in the small volume of high-field magnets is described. It is suited for measurements both in Voigt and Faraday configuration. Coupled with a pulsed...

Charge and spin dynamics in a two dimensional electron gas (2006)

Pugzlys, A, Rizo, P J, Ivanin, K, Slachter, A, Reuter, D, Wieck, A D, ...

A number of time resolved optical experiments probing and controlling the spin and charge dynamics of the high mobility two-dimensional electron gas in a GaAs/AlGaAs heterojunction are discussed....
