An essential attribute of many fractal structures is self-similarity. A Sierpinski gasket (SPG) triangle is a promising example of a fractal lattice that exhibits localized energy eigenstates. In the present work, for the first time we establish that a mixture of both extended and localized energy eigenstates can be generated yeilding mobility edges at multiple energies in presence of a time-periodic driving field. We obtain several compelling features by studying the transmission and energy eigenvalue spectra. As a possible application of our new findings, different thermoelectric properties are discussed, such as electrical conductance, thermopower, thermal conductance due to electrons and phonons. We show that our proposed method indeed exhibits highly favorable thermoelectric performance. The time-periodic driving field is assumed through an arbitrarily polarized light, and its effect is incorporated via Floquet-Bloch ansatz. All transport phenomena are worked out using Green’s function formalism following the Landauer–Büttiker prescription.

“…The Z-scan technique is an important and sensitive technique to calculate the third order nonlinear optical parameters [42, 43, 44, 45]. Using the Z-scan technique, the open and closed aperture Z-scan spectra, the nonlinear absorption coefficient and nonlinear optical refraction were calculated.…”

“…However, from the closed aperture Z-scan spectrum with pre focal valley and post focal peak indicates a self focusing process. It is a positive sign for nonlinear refraction [45]. To find out the nonlinear refractive index of grown pure and 1 mol % of NaCl doped SA crystals, the difference of the normalized peak and valley transmissions (ΔT p-v ) was calculated using the relation:…”

“…The positive sign of the nonlinear refractive index (n 2 ) indicates the self focusing nature of the crystals. This may have an advantage in practical devices, by providing remote sensing and lightning control [45, 46]. From the open aperture Z-scan curve, the nonlinear absorption coefficient (β) is 2.563 × 10 −4 m/W for pure SA and 2.909 × 10 −4 m/W for 1 mol % of NaCl doped SA crystal.…”

Single crystals of pure and NaCl doped sulphamic acid (SA) were grown by slow evaporation method at room temperature. The lattice parameters and structure were determined by using single crystal and powder X-ray diffraction analyses. The presence of dopant in the SA lattice was affirmed by EDAX analysis. UV-Vis spectra show maximum transmittance in the visible region. The band gap energies were found to be 6.06 eV and 5.70 eV for pure and NaCl doped SA crystals respectively. From the PL specta the emission were observed at 335 and 424 nm for pure and 340 and 428 nm for doped SA crystal. The thermal stability of the grown crystals were analyzed by thermogravimetric and differential thermal analysis (TGA/DTA) and revealed that the grown crystals were thermally stable up to 331 °C and 334 °C for pure and NaCl doped SA. Vickers microhardness study reveals that the hardness of the crystals is increase with increasing load. The photoconductivity study shows that the grown crystals are negative photoconductive nature. The Laser Damage Threshold (LDT) indicates the grown crystals have good resistance to laser radiation than a standard Potassium dihydrogen phosphate (KDP) crystal. The Z-scan technique was employed to determine the nonlinear refractive index, nonlinear optical absorption and third order nonlinear optical (TONLO) susceptibility of the grown crystals using He–Ne laser.

Chalcones are the main component of some natural compounds. The title compound, 3-(2,5-dimethoxyphenyl)-1-(naphthalen-2-yl)prop-2-en-1-one, was synthesized and characterized. The compound (C21H18O3) crystallizes in the triclinic system with the space group of P-1 (no. 2), a = 7.7705(4) Å, b = 10.2634(6) Å, c = 11.2487(6) Å, α = 79.655(5)°, β = 81.500(5)°, γ = 68.039(5)°, V = 815.28(9) Å3, Z = 2, T = 293(2) K, μ(MoKα) = 0.086 mm-1, Dcalc = 1.297 g/cm3, 9126 reflections measured (4.318° ≤ 2Θ ≤ 52.728°), 3302 unique (Rint = 0.0466, Rsigma = 0.0528) which were used in all calculations. The final R1 was 0.0568 (I > 2σ(I)) and wR2 was 0.1667 (all data). The crystal structure is stabilized by both short C-H···O inter- and intra-molecular interactions. In addition, the crystal structure is reinforced by π-π interactions. Hirshfeld surface analysis confirmed the presence of C-H···O intermolecular interactions. The two-dimensional fingerprint plots are used to visualize the individual interactions present in the molecule. DFT calculations were performed to know the energy levels of the frontier molecular orbitals (HOMO-LUMO). The energy gap between the frontier molecular orbitals shows the kinetic stability of the molecule. The chemical reactive sites are observed by generating MEP surface. Non-covalent interactions (NCIs) are analyzed using reduced density gradient (RDG) analysis.
