      Calculation of linear and nonlinear optical response of model Langmuir–Blodgett films

      Munn, RW; Shabat, Mohammed M. (AIP, 1993)
      Linear and nonlinear optical response are calculated for lattice models of Langmuir–Blodgett films. Molecules are treated as a set of five point submolecules, when interactions outside a layer are negligible. Molecular ...

      Calculations of NLO Response in Langmuir-Blodgett Films

      Munn, RW; Shabat, Mohammed M. (Royal Society of Chemistry, 1993)
      Organic materials are attractive for nonlinear optics because they offer the possibility of tailoring the molecules to modify their properties. However, this implies also that one understands how the desired material ...
    • Calculations of nonlinear optical properties of model Langmuir‐Blodgett films

      Munn, RW; Shabat, Mohammed M. (AIP, 1992)
      Calculations have been performed on models of Langmuir‐Blodgett LB films to explore how molecular nonlinear response expresses itself in film response. The molecules are treated as a string of s beads initially arranged ...
    • Design of Langmuir-Blodgett-Films for Nonlinear Optics

      Baggaley, A; Bishop, M; Clarke, Jhr; Davis, LE; King, TA; Leigh, DA; Mayers, FR; Mohebati, A; Munn, RW; Shabat, Mohammed M.; Szczur, O; West, D; Williams, JO (Gordon and Breach Science Publishers Ltd., Reading, England, 1993)
      Results are presented on the design, preparation and characterization of Langmuir-Blodgett films formed from stearyl (S) derivatives of DAN, MAP and NPP. Molecular dynamics modelling of trilayers composed of simplified ...

      Dipolar interactions in model Langmuir–Blodgett films

      Munn, RW; Shabat, Mohammed M. (AIP, 1993)
      Planewise dipole sums give the electric field at a point due to an array of electric dipole moments in a plane. Calculations are reported for model lattice structures of Langmuir–Blodgett films with elongated molecules ...
    • Structure and nonlinear optical properties of Langmuir-Blodgett films from p-nitroaniline derivatives

      Bishop, M; Clarke, Jhr; Davis, LE; King, TA; Mayers, FR; Mohebati, A; Munn, RW; Shabat, Mohammed M.; West, D; Williams, JO (Elsevier, 1992)
      Stearyl derivatives of DAN, MAP and NPP yield LB films with second-harmonic generation (SHG) coefficients measured as 7, 100 and 20 × 10−9 esu. Molecular dynamics modelling predicts molecular tilts of about 20°, decreasing ...
    • Theory of Non-linear Optical Response in Molecular Layers

      Munn, RW; Mothersdale, SE; Shabat, Mohammed M. (CRC PressI Llc, 1991)
      Nonlinear optics has provided a useful testing ground for the concept of molecular engineering. One seeks to design and synthesize molecules of high nonlinear optical response, and then to fabricate a molecular material ...
