Dynamics of Photo-excited Spins in InSb Based Quantum Wells
K. Nontapot, R. N. Kini, B. Spencer +5
We report time resolved measurements of spin relaxation in doped and undoped InSb quantum wells using degenerate and two-color magneto-optical Kerr effect techniques. We observed t…

Fabrication of GaNxAs1-x Quantum Structures by Focused Ion Beam Patterning
K. Alberi, A. Minor, M. A. Scarpulla +5
A novel approach to the fabrication of GaNxAs1-x quantum dots and wires via ion beam patterning is presented. Photomodulated reflectance spectra confirm that N can be released from…

Spin-polarized reflection of electrons in a two-dimensional electron system
Hong Chen, J. J. Heremans, J. A. Peters +5
We present a method to create spin-polarized beams of ballistic electrons in a two-dimensional electron system in the presence of spin-orbit interaction. Scattering of a spin-unpol…
