Mechanical simulation of the pressure and the relaxation to thermal equilibrium of a hot and dense rare gas cluster
Article Abstract:
A clod atomic cluster can be very rapidly heated and compressed by a hypersonic impact at a hard surface, which can be simulated by computing a classical trajectory for the motion of the atoms. The pressures up to the megabar range are computed for velocities of impact that are below the threshold for ionization of the cluster atoms.

Influence of oxygen on the crystalline-amorphous transition in gallium nitride films
Article Abstract:
The influence of oxygen on the structural evolution of GaN films is investigated using near-edge X-ray absorption fine structure (NEXAFS). Results indicate that the gallium coordination, formed by a mixture of oxide and nitride bonds is directly dependent on the concentration of oxygen in the films.
