A scattering mechanism stemming from the Stark-shift of energy levels by electric fields due to interface roughness in semiconductor quantum wells is identified. This scattering mechanism feeds off interface roughness and electric fields and modifies the well known “sixth-power” law of electron mobility degradation. This work first treats Stark-effect scattering in rough quantum wells as a pert...

Time and space resolved studies of emission from CN molecules have been carried out in the plasma produced from graphite target by 1.06 urn pulses from a Q-switched Nd:YAG laser. Depending on the laser pulse energy, time of observation and position of the sampled volume of the plasma, the features of the emission spectrum are found to change drastically. The vibrational temperature and populati...

The Stark shift of the hyperfine coupling constant is investigated for a P donor in Si far below the ionization regime in the presence of interfaces using tight-binding and band minima basis approaches and compared to the recent precision measurements. In contrast with previous effective mass-based results, the quadratic Stark coefficient obtained from both theories agrees closely with the expe...

Formed through a closed domain magnetic heterostructure on the surface of a three-dimensional topological insulator, a quantum dot permits a class of quantized interfacial states of topological origin. We find that these states exhibit a remarkable reverse Stark effect in response to an applied electric field. In particular, those topological states whose energies are within the gap exhibit pec...

We present an overview of developments using the nonresonant dynamic Stark effect within the fields of time-resolved molecular dynamics and quantum control, drawing on examples from our own recent work. Particular emphasis is placed on the notion that "dynamics" and "control" are not distinct disciplines and that a clear synergy exits between these areas which has, up to now, been somewhat unde...
