Polaron-induced lattice distortion of (In,Ga)As quantum dots by optically excited carriers
Sebastian Tiemeyer, Michael Bombeck, Michael Paulus +11
We report on a high resolution x-ray diffraction study unveiling the effect of carriers optically injected into (In,Ga)As quantum dots on the surrounding GaAs crystal matrix. We fi…
Picosecond opto-acoustic interferometry and polarimetry in high-index GaAs
A. V. Scherbakov, M. Bombeck, J. V. Jäger +6
By means of a metal opto-acoustic transducer we generate quasi-longitudinal and quasi-transverse picosecond strain pulses in a (311)-GaAs substrate and monitor their propagation by…
Magnetization precession induced by quasi-transverse picosecond strain pulses in (311) ferromagnetic (Ga,Mn)As
M. Bombeck, J. V. Jäger, A. V. Scherbakov +6
Quasi-longitudinal and quasi-transverse picosecond strain pulses injected into a ferromagnetic (311) (Ga,Mn)As film induce dynamical shear strain in the film, thereby modulating th…
Selective spin wave excitation in ferromagnetic (Ga,Mn)As layers by picosecond strain pulses
M. Bombeck, A. S. Salasyuk, B. A. Glavin +8
We demonstrate selective excitation of a spin wave mode in a ferromagnetic (Ga,Mn)As film by picosecond strain pulses. For a certain range of magnetic fields applied in the layer p…
