Synthesis and characterization of GaN using gas–solid reactions

Autor: F. J. Moura, B. C. Di Lello, I. G. Solórzano

Publikováno v: Materials Science and Engineering: B. 93:219-223

Gallium nitride powders were synthesized in a new vertical reactor to maximize contact between gas and solid phases. In the experiments, GaN powders were obtained by two different routes: (1) gas–solid reaction from Ga2O3/NH3 system; (2) gas–soli

Structural and Optical Properties of ZnO Crystals Synthesized With Controlled Size (abstract)

Autor: S. E. Guaño, A. Fischer, F. J. Moura, F. A. Ponce, I. G. Solórzano, Beverly Karplus Hartline, Renee K. Horton, Catherine M. Kaicher

Publikováno v: AIP Conference Proceedings.

ZnO grows in various nanostructural morphologies such as belts, platelets, wires, and rods, which depend on the synthesis routes and growth conditions. We report on the synthesis of highly luminescent ZnO crystallites and the correlation between the

Morphological Variations Of Nano-Scale Powder And Deposits Of Ain Produced By Vapor Phase Synthesis

Autor: B. C. Di lello, F. J. Moura, I. G. Solόrzano

Publikováno v: Microscopy and Microanalysis. 5:190-191

Aluminum Nitride (AIN) has arised as a promising synthetic material, valued for its high thermal conductivity coupled with high electrical resistivity. These properties, associated with the fact that AIN is nontoxic and has thermal expansion characte

Publikováno v: Applied Physics Letters. 91:121905

Zinc oxide tetrapod powders with high luminescent characteristics have been grown by simple evaporation and direct oxidation of zinc. Their structural and optical properties have been studied by transmission electron microscopy and by cathodoluminesc
