Download or read book Influence of Grain Boundaries on the Electrical Properties of Polycrystalline silicon Films Progress Report 1980 1981 written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in 1980/81 was carried out in three areas: (i) electron diffraction experiments on diffusion bonded (welded) boundaries; (ii) combined EBIC and high voltage transmission electron microscopy in order to investigate the correlation between structure and electrical properties and (iii) passivation of the electrical activity of crystal defects with hydrogen. The diffraction experiments did not furnish new information on the structure of grain boundaries in silicon, but were valuable as a check on the previous findings. In addition, they offered the possibility to separate double diffraction effects from boundary scattering. The combined EBIC and HVTEM experiments established (for the first time) unambiguously that coherent twin boundaries per se are not electrically active. The localized electrical activity observed in coherent twin boundaries is due to the presence of intrinsic dislocations, which are partial dislocations of the Schottky type. However, not all partial dislocations studied were electrically active, for reasons which are not completely understood. The combined EBIC and HVTEM investigations showed further (again for the first time) that many of the linear boundaries which were previously assumed to be coherent twin boundaries are second order twins, and that these twins are strongly electrically active. In passivation experiments, it is necessary to separate influence of the heat treatment from those of hydrogen. Passivation reduces the activity of some, but not of all defects. Passivation is particularly effective in reducing the electrical activity of deformation induced dislocations, which conceivably have a different core structure from grown-in dislocations.

Download or read book Crystalline Silicon written by Sukumar Basu and published by BoD – Books on Demand. This book was released on 2011-07-27 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exciting world of crystalline silicon is the source of the spectacular advancement of discrete electronic devices and solar cells. The exploitation of ever changing properties of crystalline silicon with dimensional transformation may indicate more innovative silicon based technologies in near future. For example, the discovery of nanocrystalline silicon has largely overcome the obstacles of using silicon as optoelectronic material. The further research and development is necessary to find out the treasures hidden within this material. The book presents different forms of silicon material, their preparation and properties. The modern techniques to study the surface and interface defect states, dislocations, and so on, in different crystalline forms have been highlighted in this book. This book presents basic and applied aspects of different crystalline forms of silicon in wide range of information from materials to devices.
