“…Here, on the basis of literature precedent, 29,32 we use n m ) 1, while n 1 ) 1 and n 2 ) 1.51 near 800-860 nm, and 1.53 around 400-430 nm. Finally, the nonlinear susceptibility, χ (2) , can be expressed as the linear combination of the molecular nonlinear polarizability, β, by where i, j, and k are laboratory coordinates and l, m, and n are molecular coordinates. ML(θ,φ,ψ) is the molecular-to-laboratory frame (Euler angle) transformation matrix and can be expressed as follows:…”

“…Molecular monolayer films are utilized in a host of passive and active scientific and technological applications, such as monolayer surfactants, liquid crystal films, and chemically tailored surfaces designed for (bio)chemical recognition and selection . The chemical nature of molecular monolayers ranges from that of model amphiphiles, such as eicosanoic acid, to molecular monolayers designed with complex structure and function, such as chip-based genomic sequences, biosensors, or molecular electronics components.…”

The Structure of a Tetraazapentacene Molecular Monolayer

et al. 2002

View full text Add to dashboard Cite

Langmuir molecular monolayers of a unique tetraazapentacene zwitterionic amphiphile were found to form stripe-like domains that responded strongly to an applied magnetic field. These stripe domains were transferred as Langmuir-Blodgett (LB) films to glass substrates, where they were structurally characterized using five complementary imaging techniques, including scanning second-harmonic generation (SHG) microscopy and capacitance force microscopy. The molecular orientations of adjacent single striped domains of a tetraazapentacene monolayer were determined by SHG polarization measurements. Those structures were shown to be consistent across the various imaging techniques.

“…The typical light throughput is around 5% for color LCDs. Poor light efficiency is predominantly related to the use of a color filter [1,2]. The filters always work on the absorption, and each color filter can transmit only one-third of the total light energy, which leads to only 33% of the light efficiency.…”

Two-step resonant diffraction grating designed for three-color separation in Fresnel diffraction region

et al. 2014

View full text Add to dashboard Cite

A two-step resonant diffraction grating is designed to separate the distributions of the wavelengths of 633, 532, and 488 nm in the Fresnel diffraction field using an analytical solution of the modal method, which can give a physical explanation for mode propagation in the grating region and interference at the interfaces. The energy efficiencies are 76.1% for 633 nm, 83.5% for 532 nm, and 75.6% for 488 nm at TE polarizations. The field distributions are captured by a color CMOS detector with a microscope, and the experimental results show the grating has a good color-separation performance.

“…Two different methods that have successfully demonstrated this are cholesteric liquid crystals (CLCs) and holographically formed polymer dispersed liquid crystals (H-PDLCs). In recent years, there have been a plethora of publications describing the various methods of achieving full color displays using these two technologies [2,3]. However, limitations of these two technologies are the complicated driving schemes necessary for full color cholesteric liquid crystal displays and the high switching voltages (>10 V/μm) in H-PDLCs due to the tight confinement of the liquid crystal droplets in the polymer matrix.…”

We discuss a configuration using vertically aligned deformed helix ferroelectric liquid crystals to create a tunable single panel full‐color reflective display without need for color filters or stacked panels. The narrow bandwidth of reflection coupled with the polarization insensitivity and fast response times enable strong and high purity reflection spectra. Thermal tunability is disclosed here to demonstrate potential performance of this device, followed by preliminary results of continuous in‐plane electrode tuning. The pitch deformation scaling with applied field coupled with the fast response times inherent for ferroelectrics with spontaneous polarization make this device an ideal candidate for low‐power reflective displays.
