Available in PDF, EPUB and Kindle. Book excerpt: Young's modulus, linear thermal expansion coefficient, stress, microhardness, wear resistance, adhesion and cohesion strength for thin films of As2S3, As2Se3, Ge28Sb12Se60, Ge33As12Se55 and Ge36As4S60 chalcogenide glasses thermally deposited onto unheated zinc selenide substrates have been determined. The interrelationship between mechanical parameters of the films has been studied. Wear resistance of chalcogenide films has been found to be related to the adhesive force and mechanical parameters used in the formal theory of glass strength. The effect of the additional stress arising in result of the temperature increase under friction on the wear resistance of the films has been shown.

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.

The reports covered two mjlin topics: theoretical basis of physics of non -crystalline materials and experimental results. In the framework of these major topics there were treated many subjects. concerning the physics of non-crystalline semiconductors and their specific application: -optical properties of non-crystalline semiconductors; -doping of glassy semiconductors and photoinduced effects in chalcogenide glasses and their application for practical purposes; -methods for investigation of the structure in non-crystalline semiconductors -new glassy materials for IR trasmittance and optoelectronics. Reports and communications were presented on various aspects of the theory. new physical principles. studies of the atomic structure. search and development of optoelectronics devices. Special attention was paid to the actual subject of photoinduced transformations and its applications. Experimental investigations covered a rather wide spectrum of materials and physical phenomena. As a novel item it is worth to mention the study of nonlinear optical effects in amorphous semiconducting films. The third order optical non linearities. fast photoinduced optical absorption and refraction. acusto-optic effects recently discovered in non-crystalline semiconductors could potentially be utilised for optical signal processing. The important problems of photoinduced structural transformations and related phenomena. which are very attractive and actual both from the scientific and practical points of view. received much attention in discussions at the conference.

Book Synopsis Structure-property Correlations in Metallic Glass and Amorphous Carbon Films by : Sachin Vijay Muley
Download or read book Structure-property Correlations in Metallic Glass and Amorphous Carbon Films written by Sachin Vijay Muley and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structure-property correlations are invaluable expertise to advance materials' technologies since well-designed materials offer a serious competitive edge, and robust failure analyses complement process improvements. This thesis invokes structure-property interrelationships with a focus on improving materials' performance for industrial adoption of various technologically important systems. In chapter 4, we studied the structure and properties of Zr-Cu-Al thin films synthesized by magnetron sputtering as a function of deposition parameters. In chapter 5, we investigated the structure, mechanical properties and scratch behavior in single-layered and multilayered amorphous carbon thin films made by NCD Technologies' proprietary vapor deposition method. In chapter 6, we presented a case study to identify the failure mode of upper copper weld wheels in an industrial production line which had a much shorter lifetime than the lower electrode. Vapor deposition forms metallic glasses with novel thermodynamic and kinetic stabilities unachievable through conventional routes. In chapter 4, kinetic stability in Zr-Cu-Al metallic glass thin films, indicated by their glass transition temperature, was widely varied by changing deposition rate at constant temperature. The most kinetically stable film's reduced modulus was 22[percent] higher than a glass of the same composition quenched from the liquid by melt spinning, suggesting increased density and improved thermodynamic stability. Fluctuation electron microscopy and angular correlations studies performed using coherent electron nanodiffraction attributed enhanced stability in glasses to increased nanoscale structural order at the medium range length scale, especially of icosahedral nature. Our results indicated that increased nanoscale icosahedral order contributed to resistance of glass to both glass transition and mechanical deformation. In chapter 5, the elastic modulus and hardness in single-layered amorphous carbon films were improved up to as much as 35 and 30 [percent] respectively by varying the applied bias voltage and pulse width. Film structure measured by Raman spectroscopy showed that the maxima in mechanical properties due to bias voltage was correlated to highest sp3 fraction, highest sp2 disorder and overall lowest disorder. Based on single-layer results, multilayers were developed. Nanoindentation and scratch-testing revealed that while multilayering preserved high hardness and improved friction behavior irrespective of the recipe, the scratch volume was strongly correlated with hardness.

Available in PDF, EPUB and Kindle. Book excerpt: The earliest experimental data on an oxygen-free glass have been published by Schulz-Sellack in 1870 [1]. Later on, in 1902, Wood [2], as well as Meier in 1910 [3], carried out the first researches on the optical properties of vitreous selenium. The interest in the glasses that exhibit transparency in the infrared region of the optical spectrum rose at the beginning of the twentieth century. Firstly were investigated the heavy metal oxides and the transparency limit was extended from (the case of the classical oxide glasses) up to wavelength. In order to extend this limit above the scientists tried the chemical compositions based on the elements of the sixth group of the Periodic Table, the chalcogens: sulphur, selenium and tellurium. The systematic research in the field of glasses based on chalcogens, called chalcogenide glasses, started at the middle of our century. In 1950 Frerichs [4] investigated the glass and published the paper: “New optical glasses transparent in infrared up to 12 . Several years later he started the study of the selenium glass and prepared several binary glasses with sulphur [5]. Glaze and co-workers [6] developed in 1957 the first method for the preparation of the glass at the industrial scale, while Winter-Klein [7] published reports on numerous chalcogenides prepared in the vitreous state.
