Book Description
The 1986 Advanced Study Institute on "The Physics of the two-Dimen sional Electron Gas" took place at the Conference Centre liTer Helme", close to Oostende (Belgium), from June 2 till 16, 1986. We were motivated to organize this Advanced Study Institute in view of the recent experimental and theoretical progress in the study of the two-dimensional electron gas. An additional motivation was our own theore tical interest in cyclotron resonance in two-dimensional electron systems at our institute. It is my pleasure to thank several instances and people who made this Advanced Study Institute possible. First of all, the sponsor of the Advanced Study Institute, the NATO Scientific Committee. Furthermore, the co sponsors: Agfa Gevaert, Bell Telephone Mfg. Co. N.V., Burroughs Belgium. Control Data. Digital Equipment Corporation, Esso Belgium. European Research Office (USA). Kredietbank. National Science Foundation (USA). Special thanks are due to the members of the Program Committee and the members of the Organizing Committee. I would also like to thank Mrs. H. Evans for typing assistance.

Book Description
Ongoing developments in nanofabrication technology and the availability of novel materials have led to the emergence and evolution of new topics for mesoscopic research, including scanning-tunnelling microscopic studies of few-atom metallic clusters, discrete energy level spectroscopy, the prediction of Kondo-type physics in the transport properties of quantum dots, time dependent effects, and the properties of interacting systems, e.g. of Luttinger liquids. The overall understanding of each of these areas is still incomplete; nevertheless, with the foundations laid by studies in the more traditional systems there is no doubt that these new areas will advance mesoscopic electron transport to a new phenomenological level, both experimentally and theoretically. Mesoscopic Electron Transport highlights selected areas in the field, provides a comprehensive review of such systems, and also serves as an introduction to the new and developing areas of mesoscopic electron transport.

Book Description
This thesis is focused on an experimental study of the electrical properties of a two-dimensional electron gas formed in a GaAs/AlGaAs heterostructure. Low temperature magneto-transport measurements are used to characterize the carrier density and mobility of this system. An extensive study of the temperature and current dependence of quantum-mechanical transport effects, observable at very low temperatures, is performed in the temperature range of 4.2-100 K, for measurement currents in the range of 10 nA- 100℗æA. The well-known decrease in the amplitude of the Shubnikov-de Haas effect, and an accompanying increase in the onset magnetic field of these oscillations, with increasing temperature, as well as a simultaneous suppression of the quantum-Hall effect, is observed. Similar behavior is found on increasing the measurement current. An analysis of the insulator to quantum Hall transition (I-QH), occurring in the two-dimensional electron gas at low perpendicular magnetic fields, is also reported, along with the results of investigations of electron heating based on the measurements of the energy-loss rate. This study shows that the direct I-QH transition does not always correspond to the onset of strong localization, with clear Shubnikov-de Haas oscillations being observed in the insulating regime. A linear dependence of the electron energy-loss rate and electron temperature in the temperature range of 4.2-40 K is determined, indicating that the main mechanism for electron energy relaxation is acoustic phonon scattering.

Book Description
This five-volume handbook focuses on processing techniques, characterization methods, and physical properties of thin films (thin layers of insulating, conducting, or semiconductor material). The editor has composed five separate, thematic volumes on thin films of metals, semimetals, glasses, ceramics, alloys, organics, diamonds, graphites, porous materials, noncrystalline solids, supramolecules, polymers, copolymers, biopolymers, composites, blends, activated carbons, intermetallics, chalcogenides, dyes, pigments, nanostructured materials, biomaterials, inorganic/polymer composites, organoceramics, metallocenes, disordered systems, liquid crystals, quasicrystals, and layered structures. Thin films is a field of the utmost importance in today's materials science, electrical engineering and applied solid state physics; with both research and industrial applications in microelectronics, computer manufacturing, and physical devices. Advanced, high-performance computers, high-definition TV, digital camcorders, sensitive broadband imaging systems, flat-panel displays, robotic systems, and medical electronics and diagnostics are but a few examples of miniaturized device technologies that depend the utilization of thin film materials. The Handbook of Thin Films Materials is a comprehensive reference focusing on processing techniques, characterization methods, and physical properties of these thin film materials.
