Adsorption and desorption kinetics of Ga on GaN(0001): Application of Wolkenstein theory
(Physical Review B - Condensed Matter and Materials Physics, 2010-08-26)The kinetics of Ga adsorption/desorption on GaN(0001) surfaces is investigated over the temperature range of 680-750°C using real-time spectroscopic ellipsometry. The adsorption and desorption kinetics are described in the ... -
Room temperature photoluminescence from In<inf>x</inf>Al<inf>(1-x)</inf>N films deposited by plasma-assisted molecular beam epitaxy
(Applied Physics Letters, 2014-09-29)© 2014 AIP Publishing LLC.InAlN films deposited by plasma-assisted molecular beam epitaxy exhibited a lateral composition modulation characterized by 10-12 nm diameter, honeycomb-shaped, columnar domains with Al-rich cores ... -
Surface-electrode point Paul trap
(Physical Review A - Atomic, Molecular, and Optical Physics, 2010-10-12)We present a model as well as experimental results for a surface electrode radiofrequency Paul trap that has a circular electrode geometry well suited for trapping single ions and two-dimensional planar ion crystals. The ... -
Ultraviolet-Visible Plasmonic Properties of Gallium Nanoparticles Investigated by Variable-Angle Spectroscopic and Mueller Matrix Ellipsometry
(ACS Photonics, 2014-07-16)© 2014 American Chemical Society.Self-assembled, irregular ensembles of hemispherical Ga nanoparticles (NPs) were deposited on sapphire by molecular beam epitaxy. These samples, whose constituent unimodal or bimodal distribution ...
