Abstract: A method for preparing a highly conductive layer utilizing a layer of Pt in conjunction with sputter deposited or co-evaporated WSi 2  to enhance the conductivity increase of the WSi 2  layer occurring during annealing is described. The Pt layer is deposited as a thin layer directly on top or beneath the WSi 2  layer or may be incorporated within the WSi 2  layer. During annealing platinum atoms diffuse into the WSi 2  film resulting in lower resistivity values than in comparably deposited annealed film wherein the Pt layer has been omitted.

Abstract: In a liquid crystal image display system, a fiber optic faceplate (24) which transmits light only through a well defined acceptance cone 28 MAX is optically coupled to the liquid crystal display surface of a reflective dynamic scattering mode liquid crystal display device (10). 
     In an image projector embodiment, light from an external light source (26) is directed through the faceplate (24) onto the liquid crystal display surface. Light scattered by activated (on-state) regions of the liquid crystal is substantially absorbed by the faceplate while light reflected from the non-activated (off-state) regions of the display surface is transmitted back through the faceplate to a projection lens (35) which forms an image on a viewing screen (36). 
     In a second embodiment of the invention a viewer directly observes the liquid crystal display surface under ambient light from either natural or artificial light sources. By absorbing light from unwanted sources outside its transmission acceptance cone, the faceplate prevents loss of image contrast while transmitting light from sources within its acceptance cone needed to illuminate the display.

Abstract: A layer (20) of Cd x Hg 1-x Te is grown on the surface of a substrate (21) by decomposing alkyls of cadmium and telluride in a mercury atmosphere. The substrate (21) is placed in a vessel (16) containing a mercury bath (19) with the vessel and bath at a suitable pressure and a temperature below the alkyl decomposition temperature. Hydrogen is passed through bubblers (6, 7, 25) separately containing alkyls of cadmium, telluride, and if required a dopant, into the vessel (16). The substrate (21) is independently heated (18) above the temperature of the vessel (16) so that the alkyls decompose on the substrate (21). The substrate may be CdTe, a II-VI compound or mixed II-VI alloy. The alkyls may be dimethyl cadmium, diethyl cadmium, dipropyl cadmium, dimethyl telluride, diethyl telluride, dipropyl telluride, dibutyl telluride, etc., or hydrogen substituted tellurium alkyls such as hydrogen ethyl telluride, etc.

Abstract: A laser Raman spectrophotometry system for analyzing a sample material by measuring spectrum of Raman scattering produced by the sample under irradiation of laser light includes a laser light source (2) for excitation of luminescense in addition to a laser light source (1) for the excitation of the Raman scattering, and an optical system (9) for rendering the optical path of the laser beam (5) for luminescence excitation to substantially coincide with the optical path of the laser beam (4) for the Raman scattering immediately before irradiation of the specimen (11). Luminescense spectrum brought about by the laser beam (5) for luminescence excitation is adjusted by adjusting the laser power to simulate the luminescence spectrum concurrently produced by the laser beam (4) for the excitation of Raman scattering, wherein both spectra of luminescence are subtractively combined together, to thereby cancel the luminescence component and allow only the spectrum of Raman-scattered light to be measured with a correspondingly enhanced accuracy.
