Photoconductivity in High Purity, Semiconducting CdF2
(Elsevier, 1972)
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 ...
Unified Hydrodynamic Theory for Crystals, Liquid Crystals, and Normal Fluids
(American Physical Society, 1972)
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 ...
