Physics of Low-Dimensional Semiconductor Structures by Paul N. Butcher, , available at Book Depository with free delivery worldwide. This book has been written to meet the growing interest of researchers in charge-transport properties of disordered solids, that is, materials without a long-range order in the spatial distribution of atoms. Disordered systems are very useful for various applications, particularly in low-cost large-area : Hardcover.
The book covers recent theoretical work exploring the quantum criticality of Mott and Wigner–Mott transitions, experiments on the metal–insulator transition and related phenomena in clean and dilute systems, the effect of spin and isospin degrees of freedom on low-temperature transport in two dimensions, electron transport near the 2D Mott. Anomalous quantum heat transport in a one-dimensional harmonic chain with random couplings. This behavior of phonons is similar to the electron transport in 1D disordered systems, although electrons and phonons differ in that electron transport is dominated by electrons near the Fermi level (when the temperature is not high) whereas in the Cited by: 4.

Available from UMI in association with The British Library. Requires signed TDF. The transport properties of low dimensional systems (especially wires) are investigated when the dominant scattering is due to the impurities and is elastic.
Such a situation is expected to be relevant to experiments carried out at very low (liquid Helium) temperatures.

Electron-Electron Interactions in Disordered Systems'' deals with the interplay of disorder and the Coulomb interaction. Prominent experts give state-of-the-art reviews of the theoretical and experimental work in this field and make it clear that the interplay of the two effects is essential, especially in low-dimensional Edition: 1.

Electron transport is a fundamental process that controls the intrinsic chemical and physical properties of solid materials. The surface phase becomes dominant when downsized dimensionality into cluster scale in nanomaterials, and surface chemistry plays more and more important role in regulating electron transport.

At x > x C, the electron states at the Fermi level are localized and look like that: Non-interacting electrons in a 3D ordered system ⇒delocalized electron states.

The transport properties of disordered electrons have been a subject of continuous interest within the last four decades.
In Anderson pointed out that the electronic (single-particle) wave function may become localized in space for sufficiently strong disorder. For one-dimensional systems it was later proved rigorously that all states are exponentially localized for arbitrary finite Cited by: 3.

Problems of Linear Electron (Polaron) Transport Theory in Semiconductors summarizes and discusses the development of areas in electron transport theory in semiconductors, with emphasis on the fundamental aspects of the theory and the essential physical nature of the transport processes.
The book is organized into three Edition: 1. This book treats three topics of electronic quantum transport in mesoscopic semiconductor structures: the conductance in strongly interacting and disordered two-dimensional systems and the metal insulator transition, electron transport through quantum dots and quantum rings in the Coulomb-blockade regime, and scanning probe experiments on semiconductor nanostructures at cryogenic temperatures.
To investigate geometric potentials in low dimensional electron systems, we have conducted first studies on topography dependant electron transport in complete tubes, using built in strain between lattice mismatched semiconductors.
Initial studies reveal two regimes of electron transport which are probed by a varying perpendicular magnetic by: 1. Reducing the disorder results in observation of an extra plateau/structure below the first quantisation which cannot be explained by single-electron theory - the structure.
By means of increasing the driving voltage across a 1D ballistic device it is possible to lift the momentum degeneracy and observe electrons drifting in one direction only. In this strong disordered regime, electron transport behaviors are adequately expressed by the model of Mott's 2D variable range hopping (VRH).
There are several reports about Mott's three-dimensional VRH in either semiconductor or oxide thin films. It is very difficult to observe Mott's 2D VRH in thin films because the thickness of the film is not as thin as the localization length Author: Jian-Jhong Lai, Dunliang Jian, Yen-Fu Lin, Ming-Ming Ku, Wen-Bin Jian.
