Thermal stability of Fe/Mo layers

Thermal stability of Fe/Mo layers

The thermal stability of an iron/molybdenum bilayer was determined using Rutherford backscattering spectrometry and X-ray diffraction. Substantial interdiffusion (3%) was observed upon annealing at 973 K for one hour. High temperature annealing of Fe/Mo layers in oxygen ambient is therefore not suitable for the formation of magnetite layers.

Thermal Stability of MOCVD and HVPE GaN Layers

This work represents a complete study of GaN annealed in H2, HCl, NH3 and N2. The GaN thermal behavior was evaluated by comparison of MOCVD and HVPE samples. The MOCVD films were found to obey a dissociative sublimation mechanism with only gaseous species forming, while the HVPE films reacted with ambient gases to form condensed Ga in addition to the gaseous species. Differences in crystal qual...

Thermal stability and nano-structure of metal-doped carbon layers

Carbon layers doped with Ti, V, W, and Zr to about 15 at.% were produced by means of magnetron sputter deposition, which distributes metal atoms homogeneously in the amorphous carbon matrix. The effects of thermal annealing to temperatures of 500–1300 K on the phase, crystallinity and distribution of the dopant were determined. X-ray diffraction (XRD), MeV ion beam analysis (IBA), and extended ...

Improvement of Thermal Stability of BCG Vaccine

Background: Thermal stability (TS) is a part of the BCG vaccine characterization by which the consistency of process in BCG vaccine production could be confirmed. To enhance the TS of the vaccine, some prevalent stabilizers in different concentrations were added to the final formulation of BCG bulk prior to Freeze-drying process. We found a formulation more effective than the current stabilizer...
