Download or read book Quantized Semiconductor Structures written by Lairenlakpam Joyprakash Singh and published by LAP Lambert Academic Publishing. This book was released on 2015-04-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the theoretical study of low dimensional quantum effect devices having quantum confinements in one- two- and three- dimensions of the wave vector space such as quantum wells, metal oxide semiconductor field effect transistors, quantum wires, quantum dots, magnetic quantization, magneto quantum size effects, magnetic inversion layers, superlattices, quantum confined superlattices and field assisted transport in nanodevices. The electron transport in semiconductor devices is essentially determined by their respective band structures. Thus, the nature of the electronic properties become different in the aforementioned systems and varies with the magnitude of the quantizing magnetic field, the quantizing electric field and other types of quantum confined structures. Though various aspects of degenerate electron gases have extensively been reported, nevertheless, it appears from the literature that few other electronic properties of quantized structures have still greater promise for future research work. Keeping this in view, the author undertook theoretical investigations of few electronic properties of quantized semiconductor structures and related phenomena.

This book was released on 2014-07-30 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the Einstein Relation(ER) in two-dimensional (2-D) Heavily Doped (HD) Quantized Structures. The materials considered are quantized structures of HD non-linear optical, III-V, II-VI, Ge, Te, Platinum Antimonide, stressed materials, GaP, Gallium Antimonide, II-V, Bismuth Telluride together with various types of HD superlattices and their Quantized counterparts respectively. The ER in HD opto-electronic materials and their nanostructures is studied in the presence of strong light waves and intense electric fields on the basis of newly formulated electron dispersion laws that control the studies of such quantum effect devices. The suggestion for the experimental determination of HD 2D and 3D ERs and the importance of measurement of band gap in HD optoelectronic materials under intense built-in electric field in nanodevices and strong external photo excitation (for measuring photon induced physical properties) are also discussed in this context. The influence of crossed electric and quantizing magnetic fields on the ER of the different 2D HD quantized structures (quantum wells, inversion and accumulation layers, quantum well HD superlattices and nipi structures) under different physical conditions is discussed in detail. This monograph contains 100 open research problems which form the integral part of the text and are useful for both Ph.D aspirants and researchers in the fields of condensed matter physics, solid-state sciences, materials science, nano-science and technology and allied fields.

This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Advanced Study Institute on the Electronic Properties of Multilayers and Low Dimensional Semiconductor Structures focussed on several of the most active areas in modern semiconductor physics. These included resonant tunnelling and superlattice phenomena and the topics of ballistic transport, quantised conductance and anomalous magnetoresistance effects in laterally gated two-dimensional electron systems. Although the main emphasis was on fundamental physics, a series of supporting lectures described the underlying technology (Molecular Beam Epitaxy, Metallo-Organic Chemical Vapour Deposition, Electron Beam Lithography and other advanced processing technologies). Actual and potential applications of low dimensional structures in optoelectronic and high frequency devices were also discussed. The ASI took the form of a series of lectures of about fifty minutes' duration which were given by senior researchers from a wide range of countries. Most of the lectures are recorded in these Proceedings. The younger members of the Institute made the predominant contribution to the discussion sessions following each lecture and, in addition, provided most of the fifty-five papers that were presented in two lively poster sessions. The ASl emphasised the impressive way in which this research field has developed through the fruitful interaction of theory, experiment and semiconductor device technology. Many of the talks demonstrated both the effectiveness and limitations of semiclassical concepts in describing the quantum phenomena exhibited by electrons in low dimensional structures.

This book was released on 2001 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electron effective state density N(ss) and dependence of the h(omega(x)) vs the Fermi energy have been also analyzed. As we have found out the state density doesn't have any noticeable energy dependence and N(ss) ^ 2m/ph(2), while the parameter h(omega(x)) rapidly drops from 100 meV down to 1 meV with the Fermi energy decreasing. The latter means that reducing of the FP screening leads to the saddle transformation into the narrow and long ballistic channel and thus detemines the conductance behavior vs the gate voltage and temperature.

This book was released on 2021-12-17 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of the scanning tunneling microscope, nanoscience became an important discipline. Single atoms could be manipulated in a controlled manner, and it became possible to change matter at its 'ultimate' level; it is the level on which the properties of matter emerge. This possibility enables to construct and to produce devices, materials, etc. with very small sizes and completely new properties. That opens up new perspectives for technology and is in particular relevant in connection with nano-engineering.Nanosystems are unimaginably small and very fast. No doubt, this is an important characteristic. But there is another feature, possibly more relevant, in connection with nanoscience and nanotechnology. The essential point here is that we work at the 'ultimate level'. This is the smallest level at which the properties of our world emerge, at which functional matter can exist. In particular, at this level biological individuality comes into existence. This situation can be expressed in absolute terms: This is not only the strongest material ever made, this is the strongest material it will ever be possible to make (D Ratner and M Ratner, Nanotechnology and Homeland Security). This is a very general statement. All aspects of matter are concerned here. Through the variation of the composition various forms of matter emerge with different items.Nanosystems are usually small, but they offer nevertheless the possibility to vary the structure of atomic (molecular) ensembles, creating a diversity of new material-specific properties. A large variety of experimental possibilities come into play and flexible theoretical tools are needed at the basic level. This is reflected in the different disciplines: In nanoscience and nanotechnology we have various directions: Materials science, functional nanomaterials, nanoparticles, food chemistry, medicine with brain research, quantum and molecular computing, bioinformatics, magnetic nanostructures, nano-optics, nano-electronics, etc.The properties of matter, which are involved within these nanodisciplines, are ultimate in character, i.e., their characteristic properties come into existence at this level. The book is organized in this respect.

This book was released on 2022-03-25 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the importance of Electron Statistics (ES), which occupies a singular position in the arena of solid state sciences, in heavily doped (HD) nanostructures by applying Heisenberg’s Uncertainty Principle directly without using the complicated Density-of-States function approach as given in the literature. The materials considered are HD quantum confined nonlinear optical, III-V, II-VI, IV-VI, GaP, Ge, PtSb2, stressed materials, GaSb, Te, II-V, Bi2Te3, lead germanium telluride, zinc and cadmium diphosphides, and quantum confined III-V, IV-VI, II-VI and HgTe/CdTe super-lattices with graded interfaces and effective mass super-lattices. The presence of intense light waves in optoelectronics and strong electric field in nano-devices change the band structure of materials in fundamental ways, which have also been incorporated in the study of ES in HD quantized structures of optoelectronic compounds that control the studies of the HD quantum effect devices under strong fields. The influence of magnetic quantization, magneto size quantization, quantum wells, wires and dots, crossed electric and quantizing fields, intense electric field, and light waves on the ES in HD quantized structures and superlattices are discussed. The content of this book finds six different applications in the arena of nano-science and nanotechnology and the various ES dependent electronic quantities, namely the effective mass, the screening length, the Einstein relation and the elastic constants have been investigated. This book is useful for researchers, engineers and professionals in the fields of Applied Sciences, solid state and materials science, nano-science and technology, condensed matter physics, and allied fields, including courses in semiconductor nanostructures. ​

This book was released on 2011-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with the study of the energy states, wavefunctions and probability of existence of an electron in multidimensional heterostructures with specific boundary conditions through different solution techniques. To do so, the theory with briefexplanation of the Schrodinger's equation inmulti-dimensions is presented. Next differenttechniques used for solution of 1D boundary value problems are discussed. A comparison is drawn among the methods and then the best one is chosen for the remaining part. Fair amount of concern is applied to this 'Semi-Analytical' solution technique which ensures easy determination of state energy values. Simple and regular multi-dimensional structures are analyzed then. Later, more complex and irregularstructures are emphasized to establish the generality of the solution technique. Size dependence of quantized energy levels in Quantum Dash structures is given special mention for it's usefulness in the Laser technology. Comparison of the results with an established finite element method is presented as well. People looking to analyze Eigen states for nano-structures should find this book useful.
