X-ray powder diffraction measurements on silver thiogallate (AgGaS2) are made while in the temperature variety involving 301 and 772 K, a area where this compound includes a tetragonal chalcopyrite composition. Within the analysis of the X-ray diffraction traces, correct lattice parameter values are decided like a functionality of temperature. These final results allow the analysis from the thermal growth coefficients from the corresponding parameters. It really is observed that the thermal enlargement conduct of AgGaS2 is analogous to that of other AgBIIIC2VI compounds getting a relatively modest expansivity alongside the c-axis and a large one particular from the perpendicular course (αc < αa).
Ab initio modeling with the structural, electronic, and optical properties of A^ II B^ IV C_ two ^ V semiconductors
This means a very small quantum defect (three.five%). A straightforward new determine of benefit that takes into consideration thermomechanical Homes and quantum defects is proposed right here to match the resistance of products below substantial-electric power laser pumping. Therefore, Yb:CAlGO is similar to garnets and sesquioxides in regard to laser power resistance.
X-ray photoelectron spectroscopy (XPS) and X-ray emission spectroscopy (XES) procedures are utilised to analyze the electronic composition of stoichiometric niobium diselenide and autointercalating substoichiometric diselenide Nb1.27Se2. The normalization with the the two XES Se Kβtwo band and XPS valence-band spectra demonstrates that adjustments with the spectra are similar when likely from NbSe2 to Nb1.
Crystal advancement, composition, and optical Houses of recent quaternary chalcogenide nonlinear optical crystal AgGaGeS4
The conduct of functions noticed in reflectivity spectra and inside the spectral dependence with the dielectric features was analyzed for a purpose with the good Resolution composition. The experimentally noticed peaks are already tabulated and related to the Digital band framework of components computed in previous will work.
Consideration of the specific geometry with the shut packing of chalcogen atoms employing a new software for ionic radius calculation and experimental study with the evaporation reveal attributes in the thermal actions of LiMX2 crystals with M = Al, In, Ga, and X = S, Se, Te.

X-ray photoelectron Main-level and valence-band spectra for pristine and Ar+-ion irradiated surfaces of Ag2HgSnS4 one crystal grown because of the Bridgman–Stockbarger approach have been measured inside the present do the job. Ag2HgSnS4 solitary-crystalline area was uncovered to get delicate to Ar+ ion-bombardment: considerable modification in top surface layers was induced resulting in abrupt lowering the information .
