“…108 If crystals grow not by monomers but by clusters, the growth shape will depend on the cluster size, which will depend on the processing parameters such as supersaturation. The morphology of growth by clusters in solution was analysed by Barber and Petty 109,110 based on moments of momenta (MoM) for dimer, trimer, tetramer, and so on. The MoM depend on the nature of the solution, while the PBC approach is controlled by the properties of the solid or crystal.…”

A cauliflower structure is a granular film composed of spherical particles similar in size, each with numerous nanoscale nodules on its surface. The structure is produced during certain chemical vapour deposition (CVD) processes for diamond and silicon thin film growth. A classical account in terms of atomic unit deposition fails to explain the growth of such a cauliflower structure, as it requires a gas phase of much higher supersaturation than for onset of diffusion controlled growth. Another interesting and somewhat puzzling phenomenon encountered during a diamond CVD process is that while diamond is depositing on a graphite substrate, carbon atoms in the graphite itself are etched away into the vapour phase; that is, experience evaporation. Again, an elementary kinetic barrier mechanism fails to explain such CVD deposition of a less stable diamond phase combined with simultaneous evaporation of a stable graphite phase. In order to account for such puzzling CVD phenomena and others, a theory of charged clusters has been developed over the past decade as a new paradigm for thin film growth. The theory and its applications are reviewed in this work.

“…By analogy, Lithium Sodium Acid Phthlate (LiNaP), a probable third harmonic generator has been chosen for the present study because of its favorable optical properties. In general, Phthalate complexes are being widely investigated for their promising electronic and optoelectronic applications [1][2][3][4][5][6][7][8][9][10][11]. The crystallographic data for many phthalic acid complexes exists in the literature are the salts of Potassium Acid Phthalate (KAP), Sodium Acid Phthalate (NaAP), Lithium Acid Phthalate (LiAP) [12][13][14].…”

A new alkali metallo-organic single crystal of Lithium Sodium Acid Phthlate (LiNaP) complex has been synthesized from aqueous solution in the equimolar ratio 3:1:2. Transparent and bulk single crystals of dimension 9 × 4 × 2 mm Li3+ Na + crystallizes in triclinic system with a space group of Pī having cell dimensions a = 7.5451(2) Å; b = 9.8422(3) Å; c = 25.2209(7) Å; α = 80.299(2); β = 89.204(2); γ = 82.7770(10). FTIR measurement was carried out for LiNaP to study the vibrational structure of the compound. The various functional groups present in the molecule and the role of H-bonds in stabilizing the crystal structure of the compound have been explained. Optical absorption properties were studied for the grown crystal using UV-Vis-NIR spectrum. Thermal measurements were carried out for LiNaP to determine the thermal strength as well as to ascertain the hydrated nature of the crystal. Third order nonliner optical studies have also studied by Z-scan techniques. Nonlinear absorption and nonlinear refractive index were found out and the third order bulk susceptibility of compound was also estimated. The results of all studies have been discussed in detail.

“…Jessen and Küppers [26] studied acid tetraalkylammonium phthalates with X-ray and vibrational methods. It is worthwhile mentioning that relatively simple calculation of moments of momentum allows to predict the crystal habit in potassium hydrogen phthalate [27].…”
