Amorphous Ge-Sb-Se thin films fabricated by co-sputtering: Properties and photosensitivity
Original language description
Amorphous Ge-Sb-Se thin films were fabricated by a rf-magnetron co-sputtering technique employing the following cathodes: GeSe2, Sb2Se3, and Ge28Sb12Se60. The influence of the composition on the optical properties was studied. Optical properties were analyzed based on variable angle spectroscopic ellipsometry and UV-Vis-NIR spectrophotometry. The results show that the optical bandgap range 1.35-2.08 eV with corresponding refractive index ranging from 3.33 to 2.36 can be reliably covered. Furthermore, morphological and topographical properties of selenide-sputtered films studied by scanning electron microscopy and atomic force microscopy showed a good quality of fabricated films. In addition, structure of the films was controlled using Raman scattering spectroscopy. Finally, irreversible photoinduced changes by means of change in optical bandgap energy and refractive index of co-sputtered films were studied revealing the photobleaching effect in Ge-rich films when irradiated by near-bandgap light under Ar atmosphere. The photobleaching effect tends to decrease with increasing antimony content.
