✦ Synopsis

Nonlinear optical transmission at discrete frequencies (bleaching bands) has been observed in CdSe and GaAs quantum wires crystallized in chrysotile asbestos nanotubes with average diameter β‰ˆ6 nm and in nanocrystals of CdS (crystallized in the transparent molecular filter-mica with empty channels of designed diameter). The induced decrease of absorption in quantum wires has been explained by filling of the size-quantized energy bands with nonequilibrium carriers (saturation effect) and by the phase-space filling of excitons.

Effects of an external magnetic field on free induction decay (FID) and the Stark effect in GaAs/GaAlAs quantum wires have been investigated analytically. Our results show that both FID and the Stark effect become enhanced due to the presence of a magnetic field. We have also seen that the magnetic

In this work, analytical solutions for the interface longitudinal-optical (LO) phonons in cylindrical polar-semiconductor quantum wires are normalized by the standard quantization condition. Two cases are considered: polar-semiconductor quantum wires encapsulated in another polar-semiconductor and p

The optical absorption of quantum-well wires is studied theoretically. A single quantumwell wire is treated by means of the subband expansion which allows us to classify the optical transitions. The accuracy of this approximation for quantitative predictions is examined. For the first time, optical
