Coupled bloch-phonon oscillations in semiconductor superlattices
We investigate coherent Bloch oscillations in GaAs/AlxGa1-xAs superlattices with electronic miniband widths larger than the optical phonon energy. In these superlattices the Bloch frequency can be tuned into resonance with the optical phonon. Close to resonance a direct coupling of Bloch oscillations to LO phonons is observed which gives rise to the coherent excitation of LO phonons. The densit...
متن کاملDynamics of Bloch oscillations
We study the dynamics of Bloch oscillations in a one-dimensional periodic potential plus a (relatively weak) static force. The tight-binding and single-band approximations are analysed in detail, and also in a classicalized version. A number of numerically exact results obtained from wavepacket propagation are analysed and interpreted in terms of the tight-binding and single-band model, both in...
متن کاملInterband optical investigation of Bloch oscillations in semiconductor superlattices
The experimental observation of Bloch oscillations in solids was long thought to be out of experimental reach. The invention of the semiconductor superlattice has changed this situation decisively. Transport experiments performed in the past two decades have given indirect evidence for the existence of Bloch oscillations. Recently, it has been possible to directly observe Bloch oscillations in ...

متن کاملBloch oscillations and Wannier-Stark localization in semiconductor superlattices
Ever since the initial applications of quantum mechanics to the dynamics of electrons in solids, the analysis of Bloch electrons moving in a homogeneous electric field has been of central importance. By employing semiclassical arguments, in 1928 Bloch [1] demonstrated that, a wave packet given by a superposition of single-band states peaked about some quasimomentum, h̄k, moves with a group veloc...
