CONDUCTING POLYMERS. Expert is a Senior Research Specialist at The University of Utah OptoElectronic Materials Lab, which is one of the few sources of conducting polymers in the world. Unsubstituted PPV and well as DOO-PPV, DDO-PPP, and PANi are all available. These are routinely characterized by photoluminescence and FTIR as well as for quantum efficiency. CHALCOGENIDE GLASSES. Numerous combinations of arsenic sulfide and selenide as well as copper or silver ternaries are available as bulk materials and thin films. Some film compositions can be evaporated onto substrates including glass and glass/ITO. Evaporated films can also be metallized with evaporated aluminum, gold, or silver. ELECTRON BEAM LITHOGRAPHY. Under Expert's direction, capabilities are being developed for electron beam lithographic processing of semiconductor substrates using a Leo 440 scanning electron microscope. The facility is expected to be operational by mid-1999. CZOCHRALSKI METHOD. The Materials Lab celebrated the growth of their 3000th Czochralski crystal, approximately half of them done under the direction of Expert. He and his coworkers have now grown all 20 alkali halides as well as hydrides, cyanides, and a few metals. Both high purity and intentionally doped crystals are grown under controlled atmospheres, typically inert. ALKALI HALIDE. Under Expert's direction, his laboratory has now grown singles of all alkali halides. Purification techniques for starting materials include reactive atmosphere processing, zone refining, melt filtration, and vacuum sublimation. Czochralski and Bridgman methods are used for single crystal growth; atomic absorption spectrophotometry for analysis. CRYSTAL; CRYSTAL GROWTH; CRYSTALLIZATION. High purity and intentionally doped single crystals of alkali halides, hydrides and cyanides are grown by the Czochralski and Bridgman techniques under Expert's supervision. He is also directly involved in the optical characterization of compound semiconductor crystals, primarily epitaxially grown III-Vs. CYANIDE COMPOUND. Expert claims to be the world's premier authority on the synthesis, purification, and single crystal growth of alkali cyanides. HYDRIDE. Expert's laboratory is probably the world's only source of single crystal lithium hydrides. All isotopic combinations of 6Li and 7Li hydride and deuteride have been synthesized and grown here. SPECTROSCOPY; III-V SEMICONDUCTOR MATERIAL; PHOTOLUMINESCENCE. Expert uses atomic absorption spectroscopy to measure concentrations of impurities and dopants in the alkali halide crystals he produces. Current research is focused on characterizing III-V semiconductors using an number of variations of photoluminescence: conventional, time resolved, selectively excited, microwave modulated, and PLE. Absorption spectroscopy is available over the range 185 nm to 100 microns. BRIDGMAN METHOD. In cases where the Czochralski method of single crystal growth is inappropriate (primarily due to excessive volatility) Expert uses the Bridgman method of single crystal growth.
