Characterization of the ternary compounds AgGaTe2 and AgGa5Te8

Investigation of physical properties of quaternary AgGa0.5In0.5Te2 thin films deposited by thermal evaporation

“…A few studies were reported for AgInTe 2 and AgGaTe 2 thin films grown by different deposition techniques [11][12][13][14]. These are taking the attention because of their potential applications for second harmonic generation, optical parameter oscillation [15], heterojunction solar cells and infrared light sources [16,17]. In the present study, an attempt was made to investigate the structural, optical and photo-electrical properties of quaternary AgGa 0.5 In 0.5 Te 2 thin films deposited by thermal evaporation method and the results presented in this study are the typical results obtained from the five sets of the samples deposited under the same conditions.…”

Structural Properties and Morphology of the Quaternary Semiconductor AgIn4GaTe8

“…A tetragonal phase (Figure 2a), with unit cell parameters a=6.070 Å, c=12.224 Å, c/a=2.0138, and a secondary phase (Figure 2b) taking place in the orthorhombic structure with unit cell parameters a=6.274 Å, b=10.793 Å, c=14.498 Å. Although in a recent work we have shown that polycrystalline Ag(In 1-x Ga x ) 5 Te 8 may exhibit a single tetragonal structure for all x values [9], the presence of these two phases in AgIn 4 GaTe 8 is not surprising, since other authors have report that the ternary AgGa 5 Te 8 can crystallize in both tetragonal and orthorhombic structure [8,13]. The unit cell parameters obtained for the tetragonal phase in our sample depart from the values a=6.1503 Å, c=12.329 Å, and c/a=2.0046, reported for single-tetragonal AgIn 4 GaTe 8 [9].…”

Device behavior of an In/p-Ag(Ga,In)Te2/n-Si/Ag heterojunction diode

“…Therefore, other chalcopyrite materials having very similar electrical and optical properties became popular [8]. Among the several materials of this group, AgInTe 2 (AIT) and AgGaTe 2 (AGT) have proved to be stable and efficient absorber materials for polycrystalline thin film heterojunction solar cells [9][10][11][12][13].…”
