Growth and Properties of CdGa₂S₄Single Crystals

Abstract

The synthesis and crystallographic, thermodynamic and transport properties of single crystalline Rh9In4S4 were studied. The resistivity, magnetization and specific heat measurements all clearly indicate bulk superconductivity with a critical temperature, Tc ∼ 2.25 K. The Sommerfeld coefficient γ and the Debye temperature(ΘD) were found to be 34 mJ mol −1 K −2 and 217 K respectively. The observed specific heat jump, ∆C/γTc = 1.66, is larger than the expected BCS weak coupling value of 1.43. Ginzburg-Landau (GL) ratio of the low temperature GL-penetration depth, λGL≈ 5750Å5750Å, to the GL-coherence length, ξGL≈ 94Å94Å, is large: κ ∼ 60. Furthermore, we observed a peak effect in the resistivity measurement as a function of both temperature and magnetic field.

“…They are lobe shapes even second harmonic (SH) intensity is as small as 0.05 of Z-cut quartz, which can be considered as a consequence of bulk crystallization456. Broad Maker fringe pattern from surface crystallized samples46 did not appear as the precipitation of crystals in glasses. Relatively remarkable SHG signals emerged when the heat-treating durations was more than 6 hours.…”

“…Recently, chalcogenide glass-ceramics containing well-known nonlinear crystals (β-GeS 2 34, AgGeGaS 4 5, CdGa 2 S 4 6), which represented a promising avenue for future nonlinear optical technologies in the mid-IR region. In this case, the isotropic structure of glass was broken by the precipitated nonlinear crystals induced by heat treatment, which induced SHG in glass-ceramics, also induced declination of transmittance12.…”

Role of the Crystal Lattice Constants and Band Structures in the Optoelectronic Spectra of CdGa2S4 by DFT Approaches

“…The binary cadmium chalcogenides, Cd X ( X = S, Se, Te), and the ternary semiconducting compounds, AB 2 X 4 ( A = Cd, Zn, Hg; B = Al, Ga, In; X = S, Se, Te) are investigated for possessing a wide bandgap and application in the photoluminescence and optoelectronic devices . The electrophotographic layers of these semiconductors illustrate a photographic distinction with high quality and great resolution .…”
