“…It was shown that annealing and illumination lead to the increase in the energy position of the absorption edge, and to some decrease in the refractive index. In addition, it was revealed that annealing and illumination cause the Urbach energy decrease and, respectively, the decrease of structural disordering in the (Ag 3 AsS 3 ) 0.6 (As 2 S 3 ) 0.4 thin films [12].…”

“…Recently, we have reported about the structure [3], electrical conductivity [4], and optical absorption [5] in superionic Ag 3 AsS 3 -As 2 S 3 glasses and composites. Thin films in this system, like to many other similar ones, were mostly prepared via deposition onto substrates using vacuum coating techniques, i.e.…”

Abstract. (Ag 3 AsS 3 ) 0.6 (As 2 S 3 ) 0.4 thin films were deposited onto a silica substrate by using rapid thermal evaporation. The surfaces of the films were covered with Ag-rich crystalline micrometer-sized cones. The optical transmission spectra of thin films were studied within the temperature range 77…300 K. The absorption spectra in the region of its exponential behaviour were analysed, the dispersion dependences of refractive index as well as the temperature dependences of energy position of absorption edge and Urbach energy were investigated.

“…It should be noted that, in comparison with crystalline solid electrolytes, chalcogenide glasses are more technological, simple and lower-cost in production. Recently, we have reported about the structure [3], electrical conductivity [4], and optical absorption [5] in superionic Ag 3 AsS 3 -As 2 S 3 glasses and composites. X-ray studies have manifested the glasses of Ag-As-S system to get separated after adding the proustite Ag 3 AsS 3 crystal to the base As 2 S 3 glass [4].…”

Abstract. (Ag 3 AsS 3 ) x (As 2 S 3 ) 1-x (x = 0.3; 0.6; 0.9) thin films were deposited onto a silica substrate by rapid thermal evaporation. The amount of Ag-rich crystalline phase precipitates on the surfaces of the films increases with Ag 3 AsS 3 content. It has been shown that the absorption edge spectra are described by the Urbach rule. The temperature behaviour of absorption spectra was studied, the temperature dependences of energy position of absorption edge and Urbach energy were also investigated. The influence of compositional disordering due to Ag 3 AsS 3 introduction into As 2 S 3 on the optical parameters of (Ag 3 AsS 3 ) x (As 2 S 3 ) 1-x thin films were analyzsed. The spectral, temperature and compositional behaviour of refractive index for (Ag 3 AsS 3 ) x (As 2 S 3 ) 1-x thin films were studied.

TOFMS was shown to be a useful technique to study the generation of Ag(m)As(n)S(x )clusters. SEM, TEM and EDX analysis proved that the structure of AgA(s)S2 glass is ‘grain-like’ where grains are either: (1) Silver-rich ‘islands’ (Ag(m,) m up to 39) connected by arsenic and/or sulfur or arsenic sulfide chains or (2) silver sulfide (Ag2S)m (m = 9-20) clusters also similarly inter-connected. This obtained structural information may be useful for the development of ultra-high-density phase-change storage and memory devices using this kind of glass as a base.
