Аннотация: Equilibrium states of the system of self-assembled monolayers (SAMs) of n-alkanethiol molecules HS(CH2)(n-1)(X) with polar group X chemiabsorbed on the Au(111) crystal surface are considered. The couplings between the atoms (C, H) of the n-alkanethiols are approximated by the Lennard-Jones potential. The couplings between the n-alkanethiols and the crystal surface are approximated by the 12-3 potential. The interactions of polar groups and the self-images with the metal substrate are taken into consideration. The phase-transition temperatures, the structural order and equilibrium tilt, and the twist and azimuthal angles of the macromolecules, which depend on the dipole moments, are found.

Аннотация: Two Ising models on a rectangular lattice (sigma(1) model and sigma(2) model) linked to three- and four-spin interactions are used to describe the sequence of tilted phase transitions in monolayers of amphiphilic long-chain molecules on an air-water surface. Starting from Morse atom-atom potentials self-consistent equations for basic thermal averages are derived in terms of a mean-field approximation. We employ the model for CH3(CH2)(18)COOH at two values of the molecule density and obtain all known tilted phases, including an intermediate one.

Аннотация: The n-alkanethiols CH3(CH2)(n-1) on the crystal surface of gold (111) are considered. Couplings between atoms (C, H) of the n-alkanethiols were modelled by the Morse potential, and couplings between the n-alkanethiols and the crystal surface were modelled by 12-3 potentials. Because of symmetry Z(2) of the n-alkanethiols in a tilted state, the system can be reduced to the Ising model on the triangular lattice, the phase diagram of which can be explicitly considered. Depending on the choice of the coupling parameters, the ordered state of the system may form an incommensurate or 2X1 superstructure. The temperatures of the phase transition, equilibrium tilting, twisting, and azimuthal angles are found to depend on the Morse coupling constants.

Аннотация: The energy levels and eigen wavefunctions of nitrite groups (NG) in the crystal potential of NaNO2 are found and the four-dimensional representation of the Hubbard operators for NG is constructed. The Born-Mayer and dipole-dipole interactions between NG are projected into the Hubbard operator representation and the hamiltonian of the system is formulated with the involvement of NG coupling with the translational degrees of freedom. The quantitative temperature - pressure phase diagram of crystal is obtained. The dependence of the incommensurate phase wave vector on temperature, pressure, and NG dipole moment is found as well.
