Arrayed Continuous-wave THz Photomixers
S. T. Bauerschmidt, S. Malzer, G. H. Döhler +3
We present both chip-scale and free space coherent arrays of continuous-wave THz photomixers. By altering the relative phases of the exciting laser signals, the relative THz phase…
Modulational instability and solitons in excitonic semiconductor waveguides
Oleksii A. Smyrnov, Fabio Biancalana, Stefan Malzer
Nonlinear light propagation in a single-mode micron-size waveguide made of semiconducting excitonic material has been theoretically studied in terms of exciton-polaritons by using…
On the Connection of Anisotropic Conductivity to Tip Induced Space Charge Layers in Scanning Tunneling Spectroscopy of p-doped GaAs
S. Loth, M. Wenderoth, R. G. Ulbrich +2
The electronic properties of shallow acceptors in p-doped GaAs{110} are investigated with scanning tunneling microscopy at low temperature. Shallow acceptors are known to exhibit d…
Spin lifetimes and strain-controlled spin precession of drifting electrons in zinc blende type semiconductors
M. Beck, C. Metzner, S. Malzer +1
We study the transport of spin polarized electrons in n-GaAs using spatially resolved continuous wave Faraday rotation. From the measured steady state distribution, we determine sp…
