Single-Shot Electron Diffraction using a Cold Atom Electron Source [PDF]

, 2015
Cold atom electron sources are a promising alternative to traditional photocathode sources for use in ultrafast electron diffraction due to greatly reduced electron temperature at creation, and the potential for a corresponding increase in brightness ...

The Effect of RF-Plasma Power on the Growth of III-Nitride Materials [PDF]

Eurasian Journal of Science and Engineering, 2019
In this study, n-InGaN nanorods were grown directly on p-type Si (111) substrates by plasma- assisted molecular beam epitaxy (PA-MBE). The crystal structure is investigated using the reflection of high-energy electron diffraction patterns.

Annealing-induced Fe oxide nanostructures on GaAs [PDF]

, 2005
We report the evolution of Fe oxide nanostructures on GaAs(100) upon pre- and post-growth annealing conditions. GaAs nanoscale pyramids were formed on the GaAs surface due to wet etching and thermal annealing.
