Abstract
Effective mass models with screened pair interaction give reasonable e nergies for excitons in T-shaped wires provided the effects of complex geometry are included. A sizable shift between exciton states in well s and T-shaped wires occurs due to enhancement in binding energy, conf inement in the wires, and interwire coupling.
