Improvement of structural quality of AlN layers grown on c-plane sapphire substrate by metal–organic vapor phase epitaxy using post-growth annealing with trimethylgallium

AIP Advances, 2022
AlN layers were grown on a c-plane sapphire substrate by metal–organic vapor phase epitaxy (MOVPE) at 1350 °C. The structural quality of the grown AlN layers was drastically improved by post-growth annealing in mixed hydrogen, ammonia, and ...

Analytical Transmission Electron Microscopy [PDF]

Reviews in Mineralogy and Geochemistry, 2014
Analytical transmission electron microscopy (TEM) is used to reveal sub-micrometer, internal fine structure (the microstructure or ultrastructure ) and chemistry in minerals. The amount and scale of the information which can be extracted by TEM depends critically on four parameters; the resolving power of the microscope (usually smaller than 0.3 nm ...

Coexisting multi-states in catalytic hydrogen oxidation on rhodium

Nature Communications, 2021
Catalytic reactions may exhibit oscillations in the reaction rate even at constant external parameters. Here, the authors observe and explain the coexistence of such oscillations and the steady states of catalytic activity in H2 oxidation on differently ...

Stability and activity of platinum nanoparticles in the oxygen electroreduction reaction: is size or uniformity of primary importance?

Beilstein Journal of Nanotechnology, 2021
Platinum–carbon catalysts are widely used in the manufacturing of proton-exchange membrane fuel cells. Increasing Pt/C activity and stability is an urgent task and the optimization of their structure seems to be one of the possible solutions.
