The photoconductivity spectra of high purity, semiconducting CdF2, containing low concentrations of rare-earth donors, are interpreted in terms of a shallow trap \(1260 \pm 100cm^{-1} \) below the bottom of the conduction ...

The alignment of dilauryl-, dimyristoyl-, and dipalmitoylphosphatidylcholine at various water concentrations into large oriented monodomain multilayers by annealing at elevated temperatures (Powers and Clark, 1975, Proc. ...

A brief description of the essential features of amphiphillic molecules will be presented. This will be followed by a discussion of specific physical phenomena and their relation to a number of contemporary research areas. ...

Polygonal defect arrays in lipid liquid crystals prepared from dipalmitoyl-, dimyristoyl-, and dilaurylphosphatidylcholine with various concentrations of water have been observed and characterized using optical microscopy. ...

Brillouin-scattering results are reported for monodomain samples of \(\beta\)-methyl butyl p [(p-methoxy benzylidine)amino] cinnamate in both the smectic-A and -B phases. For both phases theoretical predictions are confirmed ...

The six fundamental bands of \(CH_3I\) and \(CD_3I\), both as pure liquids and in solution with \(CS_2\), have been studied in order to obtain information about the molecular rotational and vibrational dynamics. Emphasis ...

Distortions of the plane texture of smectic-A and cholesteric liquid crystals are shown to combine with the uniaxial birefringence of the plane texture to produce a strong characteristic light-scattering effect. We have ...

Raman-scattering techniques have been used to obtain a new quantitative measure of orientational statistics of individual molecules in a nematic liquid crystal. A marked discrepancy is observed between these measurements ...

A unified hydrodynamic theory is presented that is appropriate for crystals; smectic, cholesteric, and nematic liquid crystals; glasses; and normal fluids. In the theory, the increased spatial degeneracy as the system ...

\(Eu^{3+}\) in the insulating \(CdF_2\) host. Optical absorption and EPR measurements of semiconducting \(CdF_2:Eu\) are the bases of a model of this semiconductor.
