The Quantum Wires (QWs) occupy a central position in the whole field of nanoscience and technology. In this edited book, in Chapter 1, the Fowler-Nordheim Field Emission from QWs has been studied and, in Chapter 2, the Effective Mass in Heavily Doped (HD) QWs has been investigated. The importance of Dispersion Relations is already well-known since the inception of Solid State Science, which has been studied in Chapter 3 in QWs of technologically important Non- Parabolic compounds. The Diffusivity Mobility Ratio and the Magneto Thermoelectric Power in QWs have been investigated in Chapters 4 and 5, respectively. In Chapters 6 and 7, the density-of-states function in HD superlattices in the presence of electric field has been explored as well as the Quantum Capacitance in Quantum Wire Field Effect Transistors. The importance of Einstein's Photoemission is already well-known and has been studied from Heavily Doped QWs in Chapter 8. In Chapter 9, the Magnetic susceptibility in the Magnetic Susceptibilities in QWs has been explored and, lastly, Chapter 10 discusses the Heisenberg's Uncertainty Principle (HUP) and the Carrier Contribution to the Elastic Constants in HD Opto electronic QWs. This edited book is written for graduate and post graduate students, researchers, engineers and professionals in the fields of mechanical engineering, electrical and electronic engineering, semiconductors and related areas, nano-electronics, condensed matter physics, solid state sciences, materials science, nanoscience and technology and nano-structured materials in general.

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. ​
