چکیده

In this study, we used the FP-LAPW technique based on density functional theory applied in WIEN2k code to examine structural, electronic, elastic, and thermoelectric properties of cubic double perovskite Rb2InBiX6 (X = Cl, Br) compounds. The structural stability was confirmed from tolerance factor, formation energy, phonon dispersion. exchange-correlation potentials LDA, GGA, mBJ, HSE were estimate electronic properties. According band structure computed gap using are 1.61 eV, 1.81 eV for Rb2InBiCl6 1.22 1.32 Rb2InBiBr6 compounds, respectively. mechanical materials under examination reflected by calculated elastic constants. estimated bulk modulus-to-shear modulus ratios 2.13 3.65, This indicates that examined compounds ductile nature. optical terms real imaginary dielectric functions, refractive index, absorption coefficient computed, indicating they might be employed optoelectronic photovoltaic applications. temperature range 200–800 K, electrical conductivity, Seebeck coefficient, thermal power factor (PF) analysed. Relatively high PFs about 2.7 × 1010 W/K2 ms 3.1 obtained suggesting these viable usage devices. Both showed strong patterns excellent PF signifying suitable

Electronic properties of PbX₃CH₃NH₃ (X = Cl, Br, I) compounds for photovoltaic and photocatalytic applications.

Since the discovery of their excellent performance as the light-absorbing semiconducting component in photovoltaic cells, the PbX3CH3NH3 (X = I, Br, Cl) perovskites have received renewed attention. The five polymorphs stable above 200 K - the tetragonal phases for X = I, Br, Cl and the cubic phases for X = I, Br - were studied using periodic DFT calculations involving hybrid functionals (PBE0 a...

Electronic structures and optical properties of BiOX (X = F, Cl, Br, I) via DFT calculations

Based on the density functional theory (DFT), the lattice constants and atomic positions of BiOX (X = F, Cl, Br, I) species have been optimized, and the electronic and optical properties of the relaxed species have been calculated, with Bi 5d states considered or not. Relaxation generally results in the shrinkage in a and the expansion of c. Relaxed BiOCl, BiOBr, and BiOI present indirect band ...

Low energy electron energy-loss spectroscopy of CF3X (X=Cl,Br).

We report threshold electron energy-loss spectra for the fluorohalomethanes CF3X (X=Cl,Br). Measurements were made at incident electron energies of 30 and 100 eV in energy-loss range of 4-14 eV, and at scattering angles of 4 degrees and 15 degrees. Several new electronic transitions are observed which are ascribable to excitation of low-lying states as well as are intrinsically overlapped in th...
