Optically and thermally induced changes of structure, linear and non-linear optical properties of chalcogenides thin films
TL;DR: The spectral dependence of third-order nonlinear susceptibilities of amorphous As-S thin films was evaluated from changes of index of refraction using Miller's rule as discussed by the authors.

Thin chalcogenide films prepared by pulsed laser deposition – new amorphous materials applicable in optoelectronics and chemical sensors
TL;DR: In this paper, the authors present the principles, advantages, applications and drawbacks of pulsed laser deposition (PLD) technique for thin films preparation, including rare-earth and Ag-doped chalcogenide films.

TL;DR: In this paper, the vibrational modes observed in amorphous Ge-Sb-Te films are attributed, apart from defective octahedral coordination, to GeTe 4− n Ge n ( n ǫ = 1, 2, eventually 0) corner-and/or edge-sharing tetrahedra and SbTe 3 pyramidal entities, the latter dominated Raman spectra of all the films containing Sb 2 Te 3.

Optical properties and phase change transition in Ge2Sb2Te5 flash evaporated thin films studied by temperature dependent spectroscopic ellipsometry
TL;DR: In this article, the optical properties of as-prepared (amorphous) and thermally crystallized (fcc) flash evaporated Ge2Sb2Te5 thin films using variable angle spectroscopic ellipsometry in the photon energy range 0.54-4.13 eV.
