چکیده

We study theoretically the effect of thermal population on the emission spectrum of single CdSe nanocrystals. Quantum confinement leads to nonsimple emission band shapes, which have different characteristics for excitons, biexcitons, positive, and negative trions. These effects are particularly pronounced in nanorods. The maximum of the emission band is not necessarily centered at the fundamental transition energy.

Optical characterization of type-II CdTe/CdSe/CdTe heterostructure nanorods

The optical characteristics of an indirect type II transition in a series of size and shape-controlled linear CdTe/CdSe/CdTe heterostructure nanorods was studied by steady state and time resolved photoluminescence spectra. The energy and lifetime of the photoluminescence from the charge-separated band structure can be tuned by the band edges of the nanorods. Our results show a size-dependent tr...

Phase transitions and domain structures of ferroelectric nanoparticles: Phase field model incorporating strong elastic and dielectric inhomogeneity

An efficient numerical algorithm based on a Fourier spectral iterative perturbation method is proposed to accurately compute the electrostatic fields in three-dimensional (3D) microstructures with arbitrary dielectric inhomogeneity and anisotropy. The method can be conveniently implemented in phase field modeling of microstructure evolution in systems with inhomogeneous dielectric constants as ...

Direct observation of the radial breathing mode in CdSe nanorods.

We experimentally confirm the existence of the radial breathing mode in CdSe nanorods by Raman spectroscopy, which was deduced from ab initio calculations of the vibrational properties of bare CdSe nanowires and CdSe/ZnS core-shell nanowires. We calculated the modes' frequency for various diameters and measured a set of bare CdSe nanorods and CdSe/ZnS core-shell nanorods to determine the diamet...
