Atomistic Description of the Electronic Structure of T-Shaped Quantum Wires



Javier Aizpurua, G C. Bryant, W Jaskolski


We use an atomistic tight-binding theory to study arrays of T-shaped GaAs/AlGaAs quantum wires. An atomistic approach allows us to provide a theory of the electron and hole states in T-shaped wires without the approximations that limit the effective mass models. We calculate the band structure of electron and holes in periodic T-wire arrays and in arm wells and compare with the results of effective mass theory. We determine the dispersion of single states along different directions for a T-wire array and compare energies for arm-well and T-wire states.
