A study for the cartography of the interface roughness of V-shaped AlGaAs/GaAs quantum wires

A study of the ground state of quantum wires using the finite difference method

“…In a previous work we reported a study of the cartography of the interface roughness of V-shaped AlGaAs/GaAs QWRs [16]. The purpose of the present work is to present a finite difference approach for a study of the electron and heavy hole ground state of QWRs.…”
