WebBloch Oscillations in Semiconductor Superlattices. Bloch oscillations are an intriguing concept of solid state physics. When an electron experiences the force of an electric field … WebBloch oscillations, arising when electrons are driven through a perfect crystal lattice by an electric eld, are an iconic example of a coherent dynamics in quantum many-body systems[1, 2]. The oscillations are at the same frequency for all carriers, for a one-dimensional lat- tice given by != eEa=~ with Ethe eld strength and a the lattice period.
