Photo-induced formation of surface relief in amorphous As2S3 films

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...

Stress-induced formation of high-density amorphous carbon thin films

Amorphous carbon films with high sp content were deposited by magnetron sputtering and intense argon ion plating. Above a compressive stress of 13 GPa a strong increase of the density of the carbon films is observed. We explain the increase of density by a stress-induced phase transition of sp configured carbon to sp configured carbon. Preferential sputtering of the sp component in the carbon f...
