Analytical electrical model for a Si liquid crystal light valve.
An approximate analytical model has been developed which allows the voltage characteristics of the liquid crystal layer of a silicon liquid crystal light valve to be determined once the photocurrent level and device parameters have been specified. This model significantly decreases the computation time compared to current numerical techniques.
Liquid crystal light valves: A review of recent studies
Recent studies of the dynamics of nematic liquid crystals as well as in modeling of the photoactivated and CCD-addressed liquid crystal light valves are described. Recent developments in the visible to IR dynamic image converter are reviewed.
Resonant Auger decay study of C1s -> pi* core-excited OCS
The present work aims at characterizing short-lived C1s((-1)) pi*((1)) core-excited states of the OCS molecule based on the analysis of the vibrational fine structure and lineshape profiles of the high-resolution resonant Auger decay spectra recorded at the excitation energies along the C1s -> pi* resonance in the binding energy region 15-19eV. Very different behavior in terms of lineshape and resonant enhancement is observed for the (A) over tilde, (B) over tilde and (C) over tilde final states. This is explained by (1) the variation in the C-O bond lengths for the states involved in the electronic relaxation and (2) different contributions in terms of Mulliken population to the molecular orbitals determining the electronic character of the corresponding states. Since the final-state geometries are known from a number of previous experiments and ab initio calculations, the geometry of the C1s((-1)) pi*((1)) intermediate states can be predicted in analogy with e.g. the N-2, CO2 and N2O molecules.
