The effects of deposition parameters are discussed in detail, structural, optical and electrical properties have been studied. In spite of that the main goal is to get comparatively high electrical conductivity of the films, the optical properties of the films were also very important from the application point of view. For reducing the resistivity of II-VI group semiconductor thin films, doping with different materials were performed using an ion exchange method. These films have been doped with (Cu, Ag) dopant to make it p-type. The ion exchange parameters such as solution temperature, concentration and immersion time, and its effect on the speed of the process and further on the status of the resulting films was carefully determined and analyzed. Also the effect of post heat treatment, on the physical properties and the composition of the resulting films are discussed in detail. ····· 103613765

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray General relativistic mechanics in gravitational fields exterior to homogeneous spheroidal masses is developed using a new approach. Einstein`s field equations in the gravitational field exterior/interior to a static homogenous prolate spheroid are derived and a solution for the first field equations constructed. The field equations exterior and interior to the mass distribution have only one unknown function determined by the mass or pressure distribution. The obtained solutions yield the unknown function as generalizations of Newton`s gravitational scalar potential. Remarkably, this solution puts Einstein`s geometrical theory of gravity on same footing with Newton`s dynamical theory with the dependence of the field on one unknown function comparable to Newton`s gravitational scalar potential.The consequences of the homogeneous spheroidal gravitational field on the motion of test particles has been theoretically investigated. The effects of the oblate nature of the Sun and planets on some gravitational phenomena has been examined. These are gravitational time dilation, gravitational length contraction and gravitational spectral shift. ····· 103613630

The improvement is based on two mechanisms : The first is the functionlization of the detector surface by specific polymer material and the second mechanism is to improve the structure of the film on the silicon layer through developing the porous layer on n-type silicon substrate.The creation of the nanospikes silicon layer provides strong carrier - carrier interaction. The strong interaction leads to new energy relaxation and recombination channels associated with the electron hole energy transfer. This new recombination mechanism may help in the fabrication of fast response photoconductive detector. ····· 103613572
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This monograph provides supporting evidence for the importance of electronic correlations in Lithium Titanate. In chapter one Transition Metal Oxides and their interesting electric and magnetic properties are introduced. Specially, Lithium Titanate, a superconductor, and Lithium Vanadate, the only known d-electron Heavy Fermion, are introduced. In chapter two a single electron model is introduced for the conducting electrons in Lithium Titanate. The model applies a tight-binding approximation for d-electrons of Ti atoms for the alloyed compound of Lithium Titanate which is a Quantum Site Percolation (QSP) model. In chapters three and four this model is applied to a corner-sharing tetrahedral lattice to examine an alloying-induced metal-to-insulator transition. The numerical results show that this model fails to explain this transition. Finally, in chapter five the electronic interactions have been included using a combination of QSP model and Hubbard model on a corner-sharing tetrahedral lattice. Numerical results based on this model explain relatively accurately this transition which shows the important role of electronic correlations in this class of materials. ····· 103613549
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The electronic devices have such impact on our lives that it is impossible to imagine our present society without them. Nowadays, the spatial dimensions and working times of the commercial electronic devices are arraying at nanometer and picoseconds scales, so that their performance has to be understood with quantum mechanics. Quantum electron transport theories and their application to electron device modeling have matured into a well-established eld with active research, intensive software development, and vast commercial applications. On the other hand, Bohmian mechanics is a well established theory for computing quantum phenomena. Based on this formalism, in this book, a general versatile and time-dependent 3D electron transport simulator for nanoelectronic devices named BITLLES is developed . In particular, the simulator takes advantage of the use of (Bohmian) conditional wavefunctions to tackle, both, the quantum many-body and the quantum sequential measurement problems, which become of fundamental importance to understand the noise and high-frequency behavior of state-of-the-art nanoelectronic devices. ····· 103613543

This book is based on electro optical studies of rare earth doped CdSxSe1-x films, which were deposited by a simple and cost effective Chemical Bath Deposition method in the form of thin films. A highly efficient photoluminescent emission was achieved by incorporating rare earths like Holmium and Neodymium at low temperature. wet chemical routes of preparation provides ample opportunity to control the size, shape and properties of the material. Particularly the ternary compound CdS-Se has been obtained with different morphologies and tunable band gaps by controlling the bath temperature, pH, solvents and bath composition.

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray After 25 years, the microscopic mechanism of High-Tc superconductivity is still an open problem. In particular, the role of lattice vibrations is not yet clear. Many of the proposed models invoke unusual vibrational properties, such as nonlinearity in the interatomic potentials. In this thesis we present a combined experimental and theoretical study of lattice anharmonicities in cuprates. We first introduce and describe our Extended X-Ray Absorption Spectroscopy (EXAFS) experiments. We then develop a novel data analysis technique, which enables us to measure directly the nonlinearity in the interatomic potentials of the copper-oxide planes, which constitute the basic structural unit of all cuprates. Finally, based on our experimental results, we introduce a simple dynamical model of the copper-oxide layers. We study this model both analytically and numerically, showing the emergence of anharmonic localised excitations known from nonlinear physics as discrete breathers. ····· 103613455· 1 · ::::: · 20 ·· 21 ·· 22 ·· 23 ·· 24 ·· 25 ·· 26 · ::::: · 27 ·
