Book Synopsis Hydrogen in Disordered and Amorphous Solids by : Gust Bambakidis Jr.
Download or read book Hydrogen in Disordered and Amorphous Solids written by Gust Bambakidis Jr. and published by Springer. This book was released on 2013-12-19 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume in the NATO ASI series dealing with the topic of hydrogen in solids. The first (V. B76, Metal Hydrides) appeared five years ago and focussed primarily on crystalline phases of hydrided metallic systems. In the intervening period, the amorphous solid state has become an area of intense research activity, encompassing both metallic and non-metallic, e.g. semiconducting, systems. At the same time the problem of storage of hydrogen, which motivated the first ASI, continues to be important. In the case of metallic systems, there were early indications that metallic glasses and disordered alloys may be more corrosion resistant, less susceptible to embrittlement by hydrogen and have a higher hydrogen mobility than ordered metals or intermetallics. All of these properties are desirable for hydrogen storage. Subsequent research has shown that thermodynamic instability is a severe problem in many amorphous metal hydrides. The present ASI has provided an appropriate forum to focus on these issues.
Book Synopsis Optimization of the Reactive Magnetron Sputter Deposition, and Studies of Hydrogen Diffusion in Hydrogenated Amorphous Silicon Based Materials by : Yuehai Harry Liang
Download or read book Optimization of the Reactive Magnetron Sputter Deposition, and Studies of Hydrogen Diffusion in Hydrogenated Amorphous Silicon Based Materials written by Yuehai Harry Liang and published by . This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The applications of hydrogenated amorphous silicon in photovoltaic devices have been hindered due to two key problems: the light-induced metastable defect creation and poor doping. To improve these properties, I have chosen the reactive magnetron sputtering method for the growth of a-Si:H and its doped alloys. The advantages of this technique are the independent control of hydrogen incorporation via the pressure of H$\sb2$ injected into the plasma, and the energetic nature of the deposition species. The effects of growth parameters on the electrical and microstructural properties have been studied, and the films appear to be optimized. Earlier studies indicated that the mid-gap defect density of high quality a-Si:H increases from 10$\sp{15}$ cm$\sp{-3}$, and saturates at 9 x 10$\rm\sp{16}\ cm\sp{-3}$ after intense light exposure. Using reactive magnetron sputtering, I have achieved a very stable high quality a-Si:H: the saturated defect density reaches the lowest value (2$-$3 x 10$\rm\sp{16} cm\sp{-3}$) reported so far in the literature. This significant improvement of the stability could result in a high stabilized solar cell efficiency. For p$\sp+$ a-Si,C:H, films with much lower thermal activation energy (0.28-0.33 eV) have been obtained, compared with films grown by plasma enhanced chemical vapor deposition (0.4 eV). Microstructural investigation shows that the microvoid contents in these films are much less than that of high quality boron doped a-Si,C:H prepared by plasma enhanced chemical vapor deposition. I attribute the significant improvements of stability and doping efficiency of the sputtered amorphous silicon and its alloys to the better amorphous network. Hydrogen diffusion in a-Si:H has been associated with the metastable defect creation and annealing. A systematic study of hydrogen diffusion kinetics in sputtered a-Si:H is carried out for the first time. The independent control of hydrogen incorporation allows me to study explicitly the effect of hydrogen content on hydrogen diffusion kinetics. I have found that H diffusion coefficient varies strongly with the hydrogen concentration in a-Si:H film. The H diffusion coefficient is thermally activated, with the activation energy decreases from 1.6 to 1.0 eV as the hydrogen concentration increases from 1.2-12 at.%. For film with higher hydrogen content ($\sim$18 at.%), the H diffusion profile shows an exponential decay. This observation indicates that the diffusion process is deep trapping limited. Based on the experimental results, I have proposed a revised H density of states model to account for the strongly concentration dependent diffusion behavior. As the H chemical potential shifts closer to the transport level with the increase of hydrogen content, the diffusion activation energy decreases and the diffusion coefficient increases.

Download or read book World Scientific Reference Of Amorphous Materials, The: Structure, Properties, Modeling And Main Applications (In 3 Volumes) written by and published by World Scientific. This book was released on 2020-12-28 with total page 1548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amorphous solids (including glassy and non-crystalline solids) are ubiquitous since the vast majority of solids naturally occurring in our world are amorphous. Although the field is diverse and complex, this three-volume set covers the vast majority of the important concepts needed to understand these materials and their principal practical applications. One volume discusses the most important subset of amorphous insulators, namely oxide glasses; the other two volumes discuss the most important subsets of amorphous semiconductors, namely tetrahedrally coordinated amorphous semiconductors and amorphous and glassy chalcogenides. Together these three volumes provide a comprehensive set of theoretical concepts and practical information needed to become conversant in the field of amorphous materials. They are suitable for advanced graduate students, postdoctoral research associates, and researchers wishing to change fields or sub-fields.The topics covered in these three volumes include (1) concepts for understanding the structures of amorphous materials, (2) techniques to characterize the structural, electronic, and optical properties of amorphous materials, (3) the roles of defects in affecting the electronic and optical properties of amorphous materials, and (4) the concepts for understanding practical devices and other applications of amorphous materials. Applications discussed in these volumes include transistors, solar cells, displays, bolometers, fibers, non-volatile memories, vidicons, photoresists, and optical disks.
