Quantitative detection of electrically injected spin accumulation in GaAs using the magneto-optical Kerr effect
A. V. Kimel, A. Kirilyuk, P. Grabs +5
Using an ultra sensitive magneto-optical Kerr rotation setup we have observed electrical spin injection from (Zn,Mn)Se into bulk GaAs and quantified the spin injection efficiency.…
Current heating of a magnetic 2DEG in HgMnTe/HgCdTe quantum wells
Y. S. Gui, C. R. Becker, J. Liu +5
Heating caused by electrons with excess kinetic energy has been investigated in a magnetic two-dimensional electron gas, M2DEG, in HgMnTe/HgCdTe(001) quantum wells. The temperature…
Electric Field Induced Kondo Tunneling Through Double Quantum Dot
M. N. Kiselev, K. Kikoin, L. W. Molenkamp
It is shown that the resonance Kondo tunneling through a double quantum dot (DQD) with even occupation and singlet ground state may arise at a strong bias, which compensates the en…
Spin injection in the non-linear regime: band bending effects
G. Schmidt, C. Gould, P. Grabs +4
Semiconductor spintronics will need to control spin injection phenomena in the non-linear regime. In order to study these effects we have performed spin injection measurements from…
Interplay of Rashba, Zeeman and Landau splitting in a magnetic two dimensional electron gas
Y. S. Gui, C. R. Becker, J. Liu +4
The transport properties of a magnetic two dimensional electron gas consisting of a modulation doped n type HgMnTe/HgCdTe quantum well, QW, have been investigated. By analyzing the…
Observation of scaling behavior in a Coulomb blockade system
K. Flensberg, L. W. Molenkamp
We describe two experiments to study the influence of fluctuations in the electron charge on the transport properties of a quantum dot. First, we scan a device from single- to doub…
