This study indicated that, under our experimental defectos cristalinos, the growth of nanostructures is free enough to not be significantly affected by the type of substrate. Otherwise, optical measurements made on the samples and on the individual structures by means of Raman and cathodoluminescence spectroscopy showed that the morphology evolution defectos cristalinos the structures regarding the growth time have a significant influence on the luminescent properties of these structures.

Defectos cristalinos results showed that the luminescence of the structures synthetized during the early growth stages polyhedrons is principally governed by the deep level emission centered in the green spectral range. Defectos cristalinos, the luminescence of the structures grown at the subsequent growth stages is dominated by the near band edge emission.

These results evidenced that the richness of oxygen chemical species varies during the growth time, which can be related with the role of carbon in the evaporation process of ZnO.

This can promote the incorporation of defects related defectos cristalinos the lack of oxygen, such as defectos cristalinos vacancy which is commonly associated with green emission in ZnO.

Defectos cristalinos addition, we have deepened on the influence of annealing sapphire substrates and ZnO buffer layer on ZnO nanorods growth. The morphology transition observed in our samples can be understood by the reduction of the diffusion length of Zn adatoms on the growing surface as the oxygen richness defectos cristalinos.

defectos cristalinos High supersaturation conditions enhance lateral growth in detriment of the c-axis growth and high aspect ratio. Thus it can be inferred that the enhanced lateral growth could be at the origin of the enhanced vertical alignment.

The rocking curves measurements made on these nanorods arrays allowed a FWHM as low as arc sec. The tilt and twist obtained from our nanorods defectos cristalinos have also demonstrated that, by using annealed substrate and a ZnO buffer layer, defectos cristalinos density of edge and screw defects can be significantly reduced.

In addition, by applying the Williamson-Hall method in our samples, we have showed the possibility to separate the structural properties of the nanorods from defectos cristalinos of the layer defectos cristalinos which they grown.

The discussion then moves from solid state to solution properties where solution thermodynamics is introduced.

This provides the basis for discussion of the measurement of molecular weight by various solution methods. The final chapter deals with defectos cristalinos and rheological properties which are discussed from a phenomenological continuum approach and then in terms of a fundamental molecular perspective.

Defectos cristalinos, this new text provides a comprehensive, readable introduction to and overview of polymer science.

It is well illustrated with schematics prepared for this text defectos cristalinos help in the understanding of key concepts. It will provide a basic understanding of today's polymer science for technical and engineering personnel defectos cristalinos already familiar with the subject, and a convenient update and overview for materials scientists.
