Shear Deformation Helps Phase Transition in Pure Iron Thin Films with “Inactive” Surfaces: A Molecular Dynamics Study

Laser induced phase transition in iron thin films

A Molecular-dynamics Study: Nucleation Processes and Structural Transformation of Thin Iron Films on Cu(001)

We have studied the structure of monolayers of iron on a Cu(001) substrate. By means of molecular-dynamics simulations in combination with embedded-atom potentials for the description of the interactions between the atoms, we have investigated the growth of bcc domains in the iron film with decreasing temperature. It turns out that the bcc domains become larger with decreasing temperature, but ...

Annealing temperature effect on nanostructure and phase transition of Copper Oxide thin films

This paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by PVD method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°C) with a flow of 1 cm3s-1 Oxygen. The X-ray diffraction (XRD) was employed for crystallographic and phase analyses, while atomic force m...

Air stable, photosensitive, phase pure iron pyrite nanocrystal thin films for photovoltaic application.

Iron pyrite (FeS(2)) is a naturally abundant and nontoxic photovoltaic material that can potentially make devices as efficient as silicon-based ones; however existing iron pyrite photovoltaic devices contain thermodynamically unstable FeS(2) film surfaces that lead to low open circuit voltages. We report the rational synthesis of phase pure, highly crystalline cubic FeS(2) nanocrystals (NCs) us...
