“…23 We have carried out these measurements on a good quality wellpolished SA single crystal following the specific procedure described in earlier reports. 24 The frequency dependence of PPE amplitude and phase for the SA crystal is shown in the ESI. † Measurement of the PPE signal phase and amplitude enables one to determine the thermal diffusivity (α) and thermal effusivity (e).…”

Sulphamic acid (HSO 3 NH 2 ) is a potential material that exhibits excellent piezoelectric and non-linear optical properties.Nucleation and growth kinetics give valuable information about the crystal growth process, which can be employed in the growth of large size crystals. Thus we have studied its nucleation parameters such as solubility, metastable zone width, induction period, interfacial tension, critical free energy, volume free energy change, critical nucleus and found that good quality sulphamic acid crystal can be grown at low temperature. Growth of good quality crystal was done by adopting slow evaporation solution growth technique at room temperature and as a result, good quality single crystal was grown. The grown bulk single crystal of the title compound was subjected to various characterization analyses. Its unit cell dimensions were confirmed using powder X-ray diffraction. Further its crystalline perfection was assessed using high resolution X-ray diffraction and X-ray topography techniques and it was found that it is reasonably good. Its various functional groups were identified from the Fourier transform-Raman method. Nanoindentation was performed to identify the load dependence and independence of hardness (H) and Young's modulus (E) using the Oliver-Pharr method and it was found that both H and E exhibit peak load dependence. Photopyroelectric study was performed to identify its thermal properties such as thermal diffusivity (α), thermal conductivity (k), thermal effusivity (e), and heat capacity (cp). These studies reveal that it has high thermal stability compared to other single crystals. The optical homogeneity of the grown crystal was assessed using a birefringence interferometer and it was found to be reasonably good.

“…The donor-acceptor co-crystalization is quite often used as an alternative approach for inducing noncentrosymmetry in the bulk crystal that avoids the use of NLO chromophores in pure enantiomeric form. Using this approach, the 4-dimethylamino pyridinium dihydrogen phosphate crystals have grown and reported by Danuskodi et al [15,16]. The title compound is an ionic crystal in which the 4-nitrophenolate anion and the 4-dimethylamino pyridinium cation result from proton transfer and neutral 4-nitrophenol stands as a third partner.…”

Single crystals of L‐Arginine Fluoride (LAF) have been grown by the slow evaporation technique, and the crystalline perfection was studied by HRXRD. Optical absorption studies reveal the lower cut off wavelength (280 nm) and the band gap (5.1 eV). The dielectric constant and dielectric loss have been measured as a function of frequency (42 Hz–5 MHz) and temperature (307‐368K) and the activation energy is 77 μeV. The thermal transport properties such as thermal conductivity (0.88 ± 0.02 W/mK) and specific heat capacity (482±24 J/kg/K) have been estimated by the photopyroelectric technique. The nonlinear refractive index n2, is found to be of the order of 10−13 cm2/W by the Z‐scan technique.
