Jan 1, 2025 · Subsequent XRD phi (φ) scans revealed a sixfold rotational symmetry of CuGa 2 O 4 and a 30° epitaxial relationship between the film and the sapphire substrate. X-ray photoelectron spectroscopy (XPS) spectra confirmed the presence of Cu 1+, Cu 2+, and Ga 3+ oxidation states in the films.

May 13, 2019 · The crystal quality of CuGa 2 O 4 film was characterized by XRD and rocking curve measurement. Figure 1 shows the XRD θ–2θ scans patterns of the CuGa 2 O 4 film prepared on β-Ga 2 O 3 (\( \bar{2}01 \)) single-crystal substrate.

Nov 5, 2020 · The potential usage of CuGA 90–2.2 as a reusable adsorbent was demonstrated by its high adsorption efficiency (> 90%) after 5 adsorption–desorption cycles.

Mar 28, 2017 · The XRD data showed that the crystal structure changes from tetragonal chalcopyrite-type CuGaS 2 (0.5 ≤ x ≤ 0.55) to tetragonal stannite-type CuGa 5 S 8 (x = 0.8) through the mixed phase (0.60 ≤ x ≤ 0.75) of the chalcopyrite …

application in the liquid state for low-temperature bonding in microelectronics. This study investigated the i. terfacial reactions between liquid Ga and pure Cu substrates at room temperature. The directional thermal expansion behaviour of the resulting CuGa2 was analysed by syn-chrotron x-ray powder diffraction with supporting obse.

Dec 1, 2012 · Copper gallate spinels, CuGa 2 O 4, have been synthesized by two wet chemical routes: precursor method and self-propagating combustion involving a glycine-nitrate system. All complex precursors have been characterized by chemical analysis, infrared spectroscopy (IR), ultraviolet visible spectroscopy (UV–vis), electron paramagnetic resonance ...

Nov 17, 2017 · The crystal structure properties of CuGa 2 O 4 powder and post-annealed films were examined by conventional θ-2θ scan X-ray diffraction (XRD) using the Kα emission line of copper. Transmission electron microscope (TEM) was used to observe the crystalline samples in microscopic scale and corresponding selected-area electron diffraction (SAD ...

Oct 10, 2012 · The results of superior electrical properties of samples with one CuGa/In pair agree well with the observations form XRD and SEM results. In the final, the optimal value of In-to-CuGa ratio during CuGa/In layers deposition in this study is 0.625.

The structure, morphology, elemental composition and optical properties of the obtained product were characterized by using X-ray diffraction (XRD), Field Emission Scanning Electron...

Oct 15, 2019 · The ex-situ XRD (Fig. S4) also verifies the existence of LiGa at the lithiation state of the CuGa 2 electrode. During the charge process, the peaks of LiGa decrease and vanish, accompanied by the reoccurrence and intensification of the peaks of CuGa 2 , which implies the total recovery to the pristine state after the first cycle.
