Dynamics of the effective mass and the anomalous velocity in two-dimensional lattices
Y. Fang, Federico Duque-Gomez, J. E. Sipe
The semiclassical description of the dynamics of wave packets in periodic potentials and subject to an applied force relies on the concepts of effective mass and anomalous transpor…
The Franz-Keldysh effect revisited: Electroabsorption including interband coupling and excitonic effects
Federico Duque-Gomez, J. E. Sipe
We study the linear optical absorption of bulk semiconductors in the presence of a homogeneous constant (dc) electric field with an approach suitable for including excitonic effect…
Observing the Onset of Effective Mass
Rockson Chang, Shreyas Potnis, Ramon Ramos +6
The response of a particle in a periodic potential to an applied force is commonly described by an effective mass which accounts for the detailed interaction between the particle a…
Response of a particle in a one-dimensional lattice to an applied force: Dynamics of the effective mass
Federico Duque-Gomez, J. E. Sipe
We study the behaviour of the expectation value of the acceleration of a particle in a one-dimensional periodic potential when an external homogeneous force is suddenly applied. Th…
