Production of sugarcane and tropical grasses as a renewable energy source. Second quarterly report; year 2, 1978-1979

Description: Research centered on greenhouse screening of candidate grasses coupled with field-plot studies on varieties, optimal nitrogen and seeding rates, variable row spacing, and frequency of harvest. Candidate grasses were identified for short-rotation crops having potentially greater versatility than Sordan 70A (earlier maturatoon greater tolerance to moisture stress). Field-plot studies were performed on the optimization of N-fertilization and seeding rates for Sordan 70A. Field-plot data were recor… more

Hydrologic Effects of Annually Diverting 131,000 Acre-Feet of Water from Dillon Reservoir, Central Colorado

Description: From abstract: because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased diversions of water from Dillon Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reservoir each year, were reconstructed by mass balance for the 1931-77 water years. Based on the analysis, the annual maximum end-of-month drawdown below… more

Phonon-dislocation interaction

Description: Thermal conductivity measurements on LiF crystals in the temperature range 0.04 to 30 K have demonstrated that, throughout this range, thermal phonons interact with dislocations via a dynamic or resonant process which is highly frequency- and phonon-mode dependent. The results of earlier work are consistent with this interpretation.

Scattering of phonons by dislocations

Description: By 1950, an explicit effort had been launched to use lattice thermal conductivity measurements in the investigation of defect structures in solids. This technique has been highly successful, especially when combined with the measurements of other properties such as optical absorption. One exception has been the study of dislocations. Although dislocations have a profound effect on the phonon thermal conductivity, the mechanisms of the phonon-dislocation interaction are poorly understood. The mo… more

Development of high efficiency, low cost ZnSiAs/sub 2/ solar cells. Quarterly technical progress report No. 1, April 9, 1979-June 30, 1979

Description: The purpose of this study is to continue an investigation of one of the chalcopyrite semiconductors (ZnSiAs/sub 2/) in order to assess its suitability as a solar cell material. ZnSiAs/sub 2/ was previously synthesized using an open tube vapor phase epitaxial growth technique, and epitaxial layers of ZnSiAs/sub 2/ were deposited on Ge and GaAs substrates (both (001) and (112) ZnSiAs/sub 2/ on (100) and (111) substrates, respectively). Epitaxial deposits were routinely achieved while the surface … more

Description: Significant achievements are described. The first is the successful deposition of mirror-like, single phase, epitaxial ZnSiAs/sub 2/ layers on 100 Ge substrates using the organometallic growth approach. Secondly, the quality of the first layers have already exceeded that of the material grown with the original growth system. Carrier concentrations (holes) are approximately one order of magnitude lower. Thirdly, amorphous (glassy) deposits of zinc silicon arsenide, which heretofore have not been… more
