Index of refraction of Ag-doped As₃₃S₆₇ films: Measurement and analysis of dispersion

Influence of silver concentration in Ag (Sb0.33S0.67)100− thin amorphous films on photoinduced crystallization

“…3. Good quality and homogeneity of prepared (Ag)-Sb-S thin films were confirmed by optical transmission spectra where no shrinkage of interference fringes was observed [16].…”

Optical and structural properties of Ag(Cu)–As2Se3 chalcogenide films prepared by a photodoping

“…In Ref. [12], the homogeneity of the film fabricated by such a method has been approximately confirmed by secondary ion mass spectroscopy. We then evaluate the optical properties from the transmission spectra using the method developed by Swanepoel [16].…”

“…We used the method of consecutive photo-dissolution of metals, which was frequently used in previous works [11][12][13][14][15]. The a-As 2 Se 3 and metal films were deposited on a slide glass substrate by the vacuum evaporation method.…”

“…This process is understood as a kind of photoelectro-chemical 0022 reactions. The photodoping of Ag into amorphous (a-) As-S thin films has been extensively investigated by many authors [9][10][11][12][13][14]. It is recognized that, in the case of Ag/a-As 30 S 70 , the doped region has compositions near AgAsS 2 and the undoped region has hardly Ag, i.e., the depth profile of Ag concentration is a step-like shape [9,10].…”

“…In order to obtain homogeneous Ag(Cu)-As 2 Se 3 films of good optical quality, we use a method of consecutive photo-dissolution of metals into the host chalcogenide films [9][10][11][12][13][14][15], where the deposition of a thin (typically $10 nm) metal layer and illumination with light of photon energy close to that of the optical band-gap are alternately repeated. In Ref.…”
