Available in PDF, EPUB and Kindle. Book excerpt: Dielectric spectroscopy of semiconductors (DSS) employs dielectric measuring techniques to study delayed electronic transitions in and out of localised energy levels in the forbidden gap. Horizontal transitions between levels normally take place in the volume of the material and involve relatively small changes of energy. Vertical transitions between deep levels and the free bands involve energy changes of the order of half the band gap and take place mainly in interfacial space charge regions ad at semi-conductor-metal interfaces. DSS is uniquely able to resolve the spectra of these delayed transitions and measurements on semi-insulating GaAs in the frequency range .01 - 10,000 Hz and between 90 and 380 K show that none of them conforms to the expected exponential time dependence. Measurements are reported of the dielectric response in the frequency range .01 - 10,000 Hz of Schottky diodes on n-type GaAs with aluminum metallisation, with the results revealing several important deviations from the classically expected response. The most important and unexpected phenomena are the appearance of low-frequency dispersion (LFD) and of negative capacitance, which are strongly influenced by even small (0.1V) negative capacitance, which are strongly influenced by even small (0.1V) negative and positive biases, respectively. Both phenomena are linked with interfacial processes involving some form of instability arising from structural transformations at the metal semiconductor interface.

This book was released on 1987 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency dependence of trapping processes measured by the technique of Dielectric Spectroscopy of Semiconductors (DSS) reveals a ubiquitous and not generally recognized tendency to the universal fractional power laws, in complete contrast with Debye-like responses which would correspond to the normally expected exponential dependence on time. There is at present no accepted theory to account for this. We propose that one explanation may be found in a modification of our earlier model of screened hopping in which the presence of a localized electron at a trapping site affects the energy of that site through a screening process by a re-adjustment of the occupancy of other neigbouring sites. The screeningg determines the loss, while the transverse displacement of the electrons determines the polarization. Depending on the relative importance of these two processes, the exponent of the fractional power law may vary between almost zero, corresponding to very-low-loss frequency-independent behaviour at low frequencies, the so-called Low Frequency Dispersion (LFD), on the other. Electrochemical reactions may also play a role in certain interfacial processes. (Great Britain).

Available in PDF, EPUB and Kindle. Book excerpt: Dielectric Spectroscopy of Electronic Materials: Applied Physics of Dielectrics incorporates the results of four decades of research and applications of dielectric spectroscopy for solids, mostly for the investigation of materials used in electronics. The book differs from others by more detailed analysis of the features of dielectric spectra conditioned by specific mechanisms of electrical polarization and conductivity. Some original methods are presented in the simulation of frequency distributions (relaxers and oscillators), with methods proposed for various ferroelectrics frequency-temperature dielectric spectra. Also described are original methods for ferroelectrics on microwaves investigation, including the features of thin films study. The book is not burdened by complex mathematical proofs and should help readers quickly understand how to apply dielectric spectroscopy methods to their own research problems. More advanced readers may also find this book valuable as a review of the key concepts and latest advances on the topics presented. Introduces critical material characterization techniques by an expert with more than 40 years of experience in dielectric spectroscopy Reviews advances in dielectric spectroscopy methods to enable advances such as the miniaturization of electronics at the nanoscale Provides an overview of polarization mechanisms utilizing different models (i.e., oscillator and relaxation)

Available in PDF, EPUB and Kindle. Book excerpt: This volume considers experimental and theoretical dielectric studies of the structure and dynamics of complex systems. Complex systems constitute an almost universal class of materials including associated liquids, polymers, biomolecules, colloids, porous materials, doped ferroelectric crystals, nanomaterials, etc. These systems are characterized by a new "mesoscopic" length scale, intermediate between molecular and macroscopic. The mesoscopic structures of complex systems typically arise from fluctuations or competing interactions and exhibit a rich variety of static and dynamic behaviour. This growing field is interdisciplinary; it complements solid state and statistical physics, and overlaps considerably with chemistry, chemical engineering, materials science, and biology. A common theme in complex systems is that while such materials are disordered on the molecular scale and homogeneous on the macroscopic scale, they usually possess a certain degree of order on an intermediate, or mesoscopic, scale due to the delicate balance of interaction and thermal effects. In the present Volume it is shown how the dielectric spectroscopy studies of complex systems can be applied to determine both their structures and dynamics.

This book was released on 2004-11-26 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of semiconductor-layer structures using infrared ellipsometry is a rapidly growing field within optical spectroscopy. This book offers basic insights into the concepts of phonons, plasmons and polaritons, and the infrared dielectric function of semiconductors in layered structures. It describes how strain, composition, and the state of the atomic order within complex layer structures of multinary alloys can be determined from an infrared ellipsometry examination. Special emphasis is given to free-charge-carrier properties, and magneto-optical effects. A broad range of experimental examples are described, including multinary alloys of zincblende and wurtzite structure semiconductor materials, and future applications such as organic layer structures and highly correlated electron systems are proposed.
