Time Periodic Behavior of Multiband Superlattices in Static Electric Fields
Daniel W. Hone, Xian-Geng Zhao
We use an analytic perturbation expansion for the two-band system of tight binding electrons to discuss Bloch oscillations and Zener tunneling within this model. We make comparison…
ac-Field-Controlled Anderson Localization in Disordered Semiconductor Superlattices
Martin Holthaus, Gerald H. Ristow, Daniel W. Hone
An ac field, tuned exactly to resonance with the Stark ladder in an ideal tight binding lattice under strong dc bias, counteracts Wannier-Stark localization and leads to the emerge…
Ac Stark Effects and Harmonic Generation in Periodic Potentials
Martin Holthaus, Daniel W. Hone
The ac Stark effect can shift initially nonresonant minibands in semiconductor superlattices into multiphoton resonances. This effect can result in strongly enhanced generation of…
Locally Disordered Lattices in Strong ac Electric Fields
D. Hone, M. Holthaus
We develop a formalism to study the role of local defects in tight binding systems in the presence of a strong external ac electric field. It is found that the appearance and disap…
