Annealing induced phase transformations in amorphous As2S3 films

Amorphous arsenic sulphide As2S3 films prepared by ultrafast pulsed laser deposition have been vacuum annealed at a range of different temperatures. Measurements of the glass transition temperature indicate that a crystallization process initiates at annealing temperatures around 170 °C. In combination with Raman scattering analysis, we conclude that phase separation is intrinsic for our as-dep...

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...

Thin Films: Understanding Strain‐Induced Phase Transformations in BiFeO3 Thin Films (Adv. Sci. 8/2015)

Understanding Strain‐Induced Phase Transformations in BiFeO3 Thin Films

Experiments demonstrate that under large epitaxial strain a coexisting striped phase emerges in BiFeO3 thin films, which comprises a tetragonal-like (T') and an intermediate S' polymorph. It exhibits a relatively large piezoelectric response when switching between the coexisting phase and a uniform T' phase. This strain-induced phase transformation is investigated through a synergistic combinat...
