The 7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene-HDTDHP crystal is well-grown within a period of 22 days and is a monoclinic type of system of crystals with space group P21/n. The CHNSO methodology shows the formation of the entitled compound; the HDTDHP is RISE effect type of crystals with the Vicker’s proviso. The surface morphology of HDTDHP crystal is analyzed for macro scale as 200 μm scaling respectively as per SEM study. The higher amount of the dielectric constant at lower frequencies is by the existence of all polarizations; also, the dielectric loss is getting decreased with increase in temperature. The electronic filter use is 3.9987 microns for macro-influx as opto-electronic, extensive NLO type uses; as observed from UV-Visible spectrum from the cut-off and wavelength range of HDTDHP with % transmittance. The frequency doubling and tripling of the macro sample is analyzed in continuation of the Z scan and SHG of the NLO class and confirms the proper electronic functionalities. The HDTDHP crystalline sample is mainly used as photonic-macro level tool, in filters as macro-influx portrayal, in NLO utility as opto-electronic tool by the transmittance data as well as by Z scan and in frequency enhancers and projective use in displays.

The lead-free Ca(Sn x Ti1–x )O3, (0 ≤ x ≤ 0.8) sample has been successfully prepared through the ball milling process, sintered at 1200 °C for 3 h. The structural, morphological, vibrational, and microwave dielectric properties of synthesized samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and impedance analysis. All the samples have an orthorhombic phase structure with a space group of Pbnm formation, and the crystalline size and strain changes with respect to Sn4+ doping were observed in the XRD analysis. From a morphological point of view, on increasing the content “x”, the grain size reduces from 3.29 to 1.37 μm. The existence of vibrations and the bridging stretching mode of Ti–O–Ti and Ti–O–Sn both are associated with the broadband in the region below 800 cm–1 verified by FT-IR. The variation in electrons hopping off the host compound with respect to Sn4+ ions was analyzed in AC conductivity. The changes of dielectric properties such as complex permittivity, modulus spectroscopy, and dielectric loss at room temperature with a different frequency range of 1.00–2.00 GHz are discussed.

High Ionic Conduction and Polarity-Induced Piezoresponse in Layered Bimetallic Rb₄Ag₂BiBr₉ Single Crystals

The emergence of lead-free metal-halide perovskites in modern-day energy research is primarily due to their competent semiconducting and optoelectronic properties, as well as their nontoxicity and improved stability in ambient operating conditions. However, a detailed understanding of ion transport dynamics and the relaxation behavior of these materials is still elusive. In this article, we report on the single-crystal (SC) growth of a bimetallic two-dimensional layered Rb4Ag2BiBr9 and explore its dielectric, piezoelectric, and ferroelectric properties. The dielectric attributes are investigated by studying the temperature-dependent complex impedance, complex electric modulus, and AC conductivity over an extensive frequency range from 4 Hz to 8 MHz. The role of grain and grain boundaries in the effective impedance is established using the Maxwell–Wagner equivalent circuit model from the Nyquist plots. The observed electric modulus spectra are studied using the Havriliak–Nigami and the Kohlrausch–Williams–Watts formalisms to understand the ionic transport and relaxation mechanisms in Rb4Ag2BiBr9. The DC conductivity and relaxation time show Arrhenius-like behavior with the inverse temperature validating the hopping motion of ions. The values of the activation energy required for ion hopping are calculated independently from the relaxation time, hopping frequency, and DC conductivity Arrhenius plots and are in good agreement with a value of 0.47 eV. The scaling of the temperature-dependent conductivity and electric modulus spectra into a single master curve demonstrates the congruence of the ionic conduction and the relaxation phenomena at different temperatures for Rb4Ag2BiBr9. This SC demonstrates decent thermal and ambient stability up to 500 °C and 12 months, respectively. The pristine orthorhombic Rb4Ag2BiBr9 SC shows a piezoelectric amplitude value of ∼564 pm at the maximum applied bias (±10 V), and a saturation polarization of ∼0.14 nC/cm2 estimated from the piezoelectric force microscopy and polarization hysteresis loop measurement, respectively. The ferroelectric and semiconducting attributes of this material can be harnessed for prospective applications as a thin film in designing mechanical energy harvesters as well as functional photoferroelectrics, such as optical switches and ferroelectric photovoltaics.
