Chalcogenide materials form the basis of CD and DVD technologies. But an identity crisis looms in the wider field: what role do atomic reconfiguration, electronic processes and ionic movement play in these materials? 
Growth and Characterization of Amorphous Multicomponent Nitride Thin Films
This thesis explores deposition of amorphous thin films based on the two transition metal nitride systems, TiN and HfN. Additions of Si, Al and B have been investigated using three different deposiExpand
Nanoscale Electrolytic Switching in Phase‐Change Chalcogenide Films
[GRAPHICS] Reversible polarity-dependent resistance (PDR) switching in phase-change (PC) films is feasible. Nanometer-scale crystalline marks are produced in amorphous Ge2Sb2+xTe5 films by electricalExpand
Coexistence of tetrahedral- and octahedral-like sites in amorphous phase change materials
Chalcogenide alloys are materials of interest for optical recording and nonvolatile memories. We perform ab initio molecular dynamics simulations aiming at shading light onto the structure ofExpand

Pressure-induced site-selective disordering of Ge2Sb2Te5: a new insight into phase-change optical recording.
We demonstrate that , the material of choice in phase-change optical recording (such as DVD-RAM), can be rendered amorphous by the application of hydrostatic pressure. It is argued that thisExpand

Deformation of a chalcogenide glass film under optical modulated excitation
Abstract We report a significant thinning of an amorphous chalcogenide film (at least 5% of its initial thickness) from the Ge-Sb-Se system deposited by RF magnetron sputtering method on aExpand

Influence of phase transformation on structure–property relationship in quaternary In10Sb10Ag10Se70 chalcogenide films
This work reports the effect of thermal annealing (353–413 K) on structure and physical properties of thermally evaporated In10Ag10Sb10Se70 chalcogenide films. The samples were characterized by X-rayExpand
Evidence for electronic gap-driven metal-semiconductor transition in phase-change materials
TLDR
Correlations between conductivity, total system energy, and local atomic coordination revealed by experiments and long time ab initio simulations show that the structural reorganization into the amorphous state is driven by opening of an energy gap in the electronic density of states. Expand
