STRUCTURAL DEFECTS AND THEIR RELATIONSHIP TO NUCLEATION OF GaN THIN FILMS
Microstructure and extended defects in ox-GaN films grown by organometallic vapor phase epitaxy on sapphire substrates using low temperature AIN (or GaN) buffer layers have been studied using transmission electron microscopy. The types and distribution of extended defects were correlated with the film growth mode and the layer nucleation mechanism which was characterized by scanning force micro...
متن کاملبررسی تشکیل ترکیبات بینفلزی در ریختهگری مرکب دوفلزی مس و آلومینیوم
The purpose of this article is to study the formation of intermetallic compounds (IMCs) at the interface of Al/Cu bimetal produced by compound casting of molten Al in solid copper tubes. The mechanism of the intermetallic compounds formations at the interface, the effects of molten aluminum pouring temperature and solid copper tubes preheating tempreture, were investigated on the IMCs type...
متن کاملساخت نانو فیبرهای کربنی پوشیده از نانوذرات مسی با استفاده از روش نشست بخار شیمیایی حرارتی بر روی نانوذرات کاتالیستی نیکل آبکاری شده روی زیرلایه مسی
Carbon nanofibers (CNFs) decorated with Cu2O particles were grown on a Ni catalyst layer deposited on a Cu substrate by thermal. chemical vapor deposition from liquid petroleum gas. Ni catalyst nanoparticles with different sizes were produced in an electroplating system at 35˚C. These nanoparticles provide the nucleation sites for CNF growth, removing the need for a buffer layer. High temperat...
متن کاملMorphology transition and layer-by-layer growth of Rh(111).
We have observed a morphological transition in the nucleation and growth of epitaxial Rh(111). The transition occurs near 600 K and is signaled by a change in the shape of the surface features from fingered to compact. The transition appears to be related to a change in the critical nucleation size. On both sides of the transition, there lies a regime of persistent layer-by-layer growth. The ge...
متن کاملFORMATION AND GROWTH OF TITANIUM ALUMINIDE LAYER AT THE SURFACE OF TITANIUM SHEETS IMMERSED IN MOLTEN ALUMINUM
Abstract: titanium sheets in pure molten aluminum at 750 and X-Ray Diffraction Analysis results, TiAlintermetallic layer thickness increases slowly at primary stages. After that an enhanced growth rate occurs due to layercracking and disruption. Presumably, reaction starts with solving titanium into the molten aluminum causing intitanium super saturation and TiAlintermetallic layer which conseq...
