Les nanocristaux ultra-petits sont des matériaux à l'échelle nanométrique. Étant donné que la taille des nanocristaux ultra-petits est comparable ou même plus petite que le diamètre de l'exciton Bohr des matériaux, les nanocristaux ultra-petits présentent des propriétés physiques améliorées significatives, telles que les propriétés magnétiques, optiques et électroniques. Au fur et à mesure que la taille d'un nanocristal devient plus petit, l'astoichiométrie accrue et les défauts peuvent donner lieu à de nombreuses transitions de propriété intéressantes, y compris une transition métal-semi-conducteur et une transition diamagnétique à ferromagnétique. La synthèse colloïdale facile de nanocristaux ultra-petits permet d'explorer les propriétés optiques, magnétiques et électriques intéressantes de ces matériaux avec des tailles extrêmement petites à l'échelle nano. La recherche sur la chimie synthétique ainsi que les propriétés physiques de ces nanocristaux ultra-petits aident à améliorer l'applicabilité de ces nanocristaux dans les applications des appareils. Une étape nécessaire vers l'application de ces nanocristaux est leur assemblage uniforme de film. La technique efficace de dépôt de film, telle que présentée dans ce travail, facilite grandement l'application des nanocristaux dans la fabrication des appareils.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ultra-small nanocrystals are nanoscale materials. Since the size of ultra-small nanocrystals is comparable to or even smaller than the Bohr exciton diameter of the materials, ultra-small nanocrystals exhibit significant enhanced physical properties, such as magnetic, optical and electronic properties. As the size of a nanocrystal becomes smaller quantum effects, increased astoichiometry, and defects can give rise to many interesting property transitions, including a metal to semiconductor transition, and a diamagnetic to ferromagnetic transition. Facile colloidal synthesis of ultra-small nanocrystals allows one to explore the interesting optical, magnetic, and electrical properties of these materials with extremely small sizes at the nanoscale. The research on the synthetic chemistry as well as the physical properties of these ultra-small nanocrystals helps to enhance the applicability of these nanocrystals in device applications. A necessary step towards the application of these nanocrystals is their uniform film assembly. The efficient film deposition technique, as presented in this work, facilitates greatly the application of the nanocrystals in device fabrication. 148 pp. Englisch.
