Atomic Structure of the ∑5 (210)/[001] Symmetric Tilt Grain Boundary in Yttrium Aluminum Garnetits high temperature behavior. The creep rate of polycrystalline YAG. is many orders of magnitude higher than the creep rate of single crystal YAG,. indicating that grain boundaries provide a high-diffusivity path for the cations, which facilitates dislocation climb. The contributions of grain bound

Morphology and Microstructure of A1N Single Crystals on Si (111): A Combination of Surface Electron tential applications include blue light emitting diodes and ultraviolet (UV) detectors, as well as high power and high temperature electronic devices. Aluminum nitride has a wide band gap (6.2 eV). Because of its piezoelectric properties, it can also be used in field effect transistors as a gate die

Nanometer Level Characterization of Rapidly Densified Ceramics and Glass-Semiconductor Compositesvel. Clean grain boundaries and excellent grain-to-grain contact were observed in the alumina powders densified to almost full density, and very little grain growth was seen in sintered samples. High resolution TEM studies of a number of composite samples containing CdS or ZnSe nanocrystals disperse

Accommodation of Volume Changes During Diffusion-Controlled Metal Precipitation Inside an Oxide Matrcal volume changes related to this precipitation process are important. Depending on the mechanism of metal formation, it can be either negative, as in the case of substitutional mechanisms, or positive, as in the case of interstitial mechanisms. In both cases it induces large stresses during precip

Oliver Falck,Michael Fritsch,Stephan Heblichrror. The equally traditional difficulty is the large error to trial ratio. In the hope of reducing this a bit, people have turned to modelling complex processes. However, unless we are in the (unusual) position of being able to model everything the problem of deciding what the important mechanisms
