Kinetics of photoinduced surface patterning in chalcogenide thin films

Phase transformation kinetics and self-patterning in misfitting thin films

We outline a computational approach for the study of phase transformations in misfitting thin films and then investigate the kinetics of a transformation to assess the role of heterogeneous nucleation sites, formed in the vicinity of misfit dislocations, in the self-patterning of these systems. Both computer simulation and analytical methods are employed to analyze spatio-temporal correlations ...

Generalized model for photoinduced surface structure in amorphous thin films.

We present a generalized model to explain the spatial and temporal evolution of photoinduced surface structure in photosensitive amorphous thin films. The model describes these films as an incompressible viscous fluid driven by a photoinduced pressure originating from dipole rearrangement. This derivation requires only the polarizability, viscosity and surface tension of the system. Using value...

Superconducting properties of iron chalcogenide thin films.

Iron chalcogenides, binary FeSe, FeTe and ternary FeTe x Se1-x , FeTe x S1-x and FeTe:O x , are the simplest compounds amongst the recently discovered iron-based superconductors. Thin films of iron chalcogenides present many attractive features that are covered in this review, such as: (i) easy fabrication and epitaxial growth on common single-crystal substrates; (ii) strong enhancement of supe...

Photoinduced doping of thin amorphous WO, films

During cxposurc of thin amorphous WO, films to UV light, both the optical absorptivity and thc electrical conductibity increase, Using optically excited surface plasmons. we were ablc to mcnsure even subtle changes of the absorpt~vity of 10 ntn thtck films simuFtaneously with their electrical resistivity a t varivus temperatuscs. Our measurements show that the temperature dependence and thc dcp...
