The T-P phase diagrams of the halogenomethane compounds (CCl4-nBrn, n = 0, 1, 2, 4) are calculated using a mean field model. By expanding the free energy in terms of the order parameters for the transitions of the liquid (L), rhombohedral (R), face-centered cubic (FCC) and monoclinic (M) phases in those compounds, the phase line equations are derived and they are fitted to the experimental data from the literature. This method of calculating the T-P phase diagram is satisfactory to explain the T-P measurements for the halogenomethane compounds and it can also be applied to two-component systems.

Calculation of the Raman frequency and the damping constant of a coupled mode in the ferroelectric and paraelectric phases in KH(2)PO(4) KARACALİ, HUSEYİN; Kiraci, A.; Yurtseven, Hasan Hamit (Wiley, 2010-04-01) The Raman frequency of the coupled mode omega_ associated with the order parameter is calculated as a function of pressure from the mean field theory in the ferroelecric phase of KDP. Using the frequencies of the coupled mode, the pressure dependence of the damping constant Gamma_ is calculated by the proton spin lattice relaxation time and by the energy fluctuation of this mode of KDP in the ferroelectric (FE) phase. For the paraelectric (PE) phase, the Raman frequency of the coupled mode omega is calculat...
EMPIRICAL TIGHT-BINDING TOTAL ELECTRONIC-ENERGY CALCULATION FOR SINH2M (N = 1 TO 6, M = 1 TO 3) CLUSTERS Katırcıoğlu, Şenay (Wiley, 1993-06-01) The stable structures of SinH2m (n = 1 to 6, m = 1 to 3) clusters are investigated by the total electronic energy calculation using an empirical tight-binding (ETB) method. It seems that bridged H-bond models are also possible for small Si(n)H(m) clusters.
Unified theory of linear instability of anisotropic surfaces and interfaces under capillary, electrostatic, and elastostatic forces: The regrowth of epitaxial amorphous silicon Ogurtani, Tarik Omer (American Physical Society (APS), 2006-10-01) The first-order unified linear instability analysis (LISA) of the governing equation for the evolution of surfaces and interfaces under capillary, electromigration (EM), and elastostatic forces is developed. A formal treatment of the thermomigration (Soret effect) driven by the nonuniform temperature distribution caused by exothermic phase transformation (growth) at the surface and interfacial layers is presented and its apparent influence on the capillary force in connection with the stability is also esta...
Calculation of the free energies for the solid phases of ammonium halides Salihoglu, S.; Yurtseven, Hasan Hamit; Karacali, H. (Informa UK Limited, 2007-01-01) Using mean field theory, we calculate the free energies of the solid phases of ammonium halides. The temperature and pressure dependences of the free energies are obtained using experimental phase diagrams of the ammonium halides. From these dependences, we calculate numerically the specific heat as a function of temperature for the solid I-liquid, solid II-liquid and solid I-solid II transitions in the ammonium halides, in particular for NH4Cl. The critical behaviour of some other thermodynamic quantities ...
A NEW EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION - APPLICATION TO MICROCLUSTERS Erkoç, Şakir (Wiley, 1989-04-01) A new empirical many‐body potential energy function is proposed which comprises two‐ and three‐body interactions. The two‐body potential is a kind of hybrid function and the three‐body potential is expressed in terms of the two‐body interactions. The parameters of the potential energy function can be easily evaluated using dimer data and the bulk cohesive energy of the system considered. The proposed potential energy function is parameterized for several elements in f.c.c., b.c.c., and diamond structures an...
