X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and Scanning Electron Microscopy (SEM) of (CuInSe2)1?x (VSe)x Alloys (0 ?x ? 0.5)

The new P-chalcopyrite compound Cu2FeIn2Se5; synthesis, thermal analysis (DTA), and crystal structure analysis by X-ray powder diffraction (XRPD)

“…Adamantane compounds are binary, ternary, or quaternary normal tetrahedral structure compounds that are closely related to either cubic or hexagonal diamond [5]. In our laboratories, we have been studying these type of alloys from its synthesis, thermal and magnetic properties as well as their crystal structures [6][7][8][9][10][11][12][13]. Due to the great variety of possible compositions, these materials can be useful for applications such as tunable semiconductors [14], photovoltaics [15], non-linear optics [16], thermoelectrics [17], and particularly as spintronic device [18] due to the discovery of room-temperature ferromagnetism and super-paramagnetism in some of these materials [19].…”

“…1. However, others authors reported that hexagonal NiAs-like phases were observed in CuInTe 2 /MnTe, AgInTe 2 /MnTe and CuGaTe 2 /MnTe, and also cubic NaCllike phases in CuInSe 2 /MnSe, CuGaSe 2 /MnSe and CuInS 2 /MnS (see Table 1; Grima et al, 2002).…”
