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: 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.

Заглавие : Nonlinear optical characterization of spontaneously grown domain structures in SBO crystals

Аннотация: Spontaneously grown partially ordered domain structures in SBO crystals are characterized via nonlinear diffraction. Domains have the form of sheets lying in cb plane with the domain walls oriented perpendicularly to the a crystallographic axis. The thickness of domains varies in quite wide range. The effective thickness of domains contributing to the nonlinear diffraction is determined from Fourier spectrum of inverse superlattice wave vectors to lie between 180 nm and 8 microns. General properties of spatial Fourier spectrum are reproducible from one growth procedure to another, however, details of spectrum noticeably vary. Enhancement factors for random QPM are calculated and found to be of order of several thousand in the near UV.

Аннотация: Ferromagnetic Fe1-xNix(P) (x=24-65 at.%.) columns have been chemically deposited into porous polycarbonate membranes with pore diameters of 0.1-4 J.Im. The morphological characterization by TEM reveals the shape features in synthesized columns. Their magnetic perpendicular anisotropy due to the shape anisotropy of columns was observed. The dependence of macroscopic anisotropy on pore diameter and Ni content is analyzed. Approach to magnetic saturation curves and exchange constant of nanocrystalline fe?.xNix(P) columns deposited into porous pol}\:arbonate matrix are investigated.

Заглавие : Deep UV generation and fs pulses characterization us­ing strontium tetraborate
Коллективы : Nonlinear Optics and Applications
Место публикации : Nonlinear Optics and Applications V: Proceedings of the SPIE. - 2011. - С. 36. - (SPIE Optics + Optoelectronics)
Аннотация: The properties of NPC structures in strontium tetraborate are analyzed. Different types of NPC structures are revealed that possess different nonlinear properties, and their spectral dependences of frequency conversion efficiency are calculated and compared. Experimental study of these structures is reported for the process of doubling of the second harmonic of fs Ti:S laser. Tuning of generated radiation is obtained in the range 187.5 - 232.5 nm, with extreme insensitivity to the angular orientation of NPC. Behavior of tuning curve along investigated fundamental wave range is similar in all studied samples, but efficiency obtained depends on the type of structure. Conversion efficiency andspectral quality of generated radiation is experimentally shown to grow better when using NPC with improved structure. Prospects of VUV converter on a single NPC are discussed. NPCs of SBO are demonstrated to be useful for autocorrelation diagnostics both in random QPM geometry and in the geometry of nonlinear diffraction from virtual beam.
