This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of deposition temperature and in-situ post-deposition annealing on the microstructure of coevaporated Cu(InGa)Se2 thin films and on the performance of the resulting solar cell devices have been characterized. Films were deposited at substrate temperatures of 150°C, 300°C and 400°C. Films were also deposited at these temperatures and then annealed in-situ at 550°C for 10 minutes. In as -deposited films without annealing, additional XRD reflections that may be due to a polytypic modification of the chalcopyrite phase were observed. Films deposited at 150°C were Se-rich. Post-deposition annealing caused microstructural changes in all films and improved the resulting solar cells. Only films deposited at 400°C, however, yielded high-efficiency devices after post-deposition annealing that were equivalent to devices made from films grown at 550°C. Films originally deposited at 300°C yielded devices after post-deposition annealing with VOC close to that of devices made from films grown at 550°C, despite smaller grain size.
Download or read book Glancing Angle Deposition of Thin Films written by Matthew M. Hawkeye and published by John Wiley & Sons. This book was released on 2014-07-03 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a highly practical treatment of Glancing Angle Deposition (GLAD), a thin film fabrication technology optimized to produce precise nanostructures from a wide range of materials. GLAD provides an elegant method for fabricating arrays of nanoscale helices, chevrons, columns, and other porous thin film architectures using physical vapour deposition processes such as sputtering or evaporation. The book gathers existing procedures, methodologies, and experimental designs into a single, cohesive volume which will be useful both as a ready reference for those in the field and as a definitive guide for those entering it. It covers: Development and description of GLAD techniques for nanostructuring thin films Properties and characterization of nanohelices, nanoposts, and other porous films Design and engineering of optical GLAD films including fabrication and testing, and chiral films Post-deposition processing and integration to optimize film behaviour and structure Deposition systems and requirements for GLAD fabrication A patent survey, extensive relevant literature, and a survey of GLAD's wide range of material properties and diverse applications.

This book was released on 1989 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of various annealing treatments on ion beam sputter- deposited Y1Ba2CuyO(7-x)(y=3 and 5) amorphous thin films has been studied using scanning electron microscopy (SEM), X-ray diffraction and dc resistivity measurements. SEM analysis showed that the morphology of the films were clearly divided into three categories: an equiaxial grain structure, a well-oriented grid-like microstructure and a textured platelet structure. The equiaxial grain structure (random orientation according to X-ray diffraction measurements) was obtained when the film was annealed at slow heating and cooling rates in an oxygen atomosphere. The grid-like microstructure (b/c-axes oriented normal to the plane) was obtained in Cu-rich composition (y=5) by rapid thermal annealing. A textured platelet microstructure (c-axis oriented normal to the plane) was obtained using slow heating rates and by carefully controlling the gas environment at the temperature region near the orthorhombic-tetragonal transition. Thus, we have demonstrated the ability to control the morphology and orientation of the film by varying the annealing process.
