Cohesive Properties of Semiconductors Under Laser Irradiation
ISBN: 9789400968929 / Angielski / Miękka / 633 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The impact of Materials Science in our environment has probably never been as massive and decisive as it is today. In every aspect of our lives, progress has never been so dependent on the techniques involved in producing ever more sophisticated materials in ever larger quantities, nor so demanding for technologists to imagine novel processes and circumvent difficulties, or take up new challenges. Every technique is based on a physical process which is put into practice and optimized. The better we know that process, the better the optimization, and more powerful the technique. Laser...

Optical Precursors: From Classical Waves to Single Photons
ISBN: 9789814451932 / Angielski / Miękka / 79 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Ever since Einstein's special relativity in 1905, the principle of invariant light speed in vacuum has been attracting attention from a wide range of disciplines. How to interpret the principle of light speed? Is light referred to continuous light, or light pulse with definite boundaries? Recent discovery of superluminal medium triggered vigorous discussion within the Physics community. Can communication via such "superluminal channel" break the speed limit and thus violate causality principle? Or, will a single photon, which is not governed by classical laws of Physics, tend to break the...

Relativistic Electrodynamics and Differential Geometry
ISBN: 9781461291138 / Angielski / Miękka / 308 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The aim of this book is to provide a short but complete exposition of the logical structure of classical relativistic electrodynamics written in the language and spirit of coordinate-free differential geometry. The intended audience is primarily mathematicians who want a bare-bones account of the foundations of electrodynamics written in language with which they are familiar and secondarily physicists who may be curious how their old friend looks in the new clothes of the differential-geometric viewpoint which in recent years has become an important language and tool for theoretical physics....

Coherent Optical Interactions in Semiconductors
ISBN: 9781475797503 / Angielski / Miękka / 372 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The NATO Advanced Research Workshop on Coherent Optical Processes in Semiconductors was held in Cambridge, England on August 11-14,1993. The idea of holding this Workshop grew from the recent upsurge in activity on coherent transient effects in semiconductors. The development of this field reflects advances in both light sources and the quality of semiconductor structures, such that tunable optical pulses are now routinely available whose duration is shorter than the dephasing time for excitonic states in quantum wells. It was therefore no surprise to the organisers that as the programme...

Quantum Effects for Spintronic Devices Optimization
ISBN: 9783659325069 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work is mainly dedicated to the study of spin dependent transport in magnetic nanostructures. The principal objective is the optimization of the magnetoresistive performance of such structures, in order to built high density Magnetic Random Access Memories (MRAM). Nevertheless, new resistive properties are also found, that could be useful for another type of non-volatile memory device, in this case, Resistive Random Access Memories (ReRAM). The book is basically divided into two parts: the first one considers the theoretical analysis of perfect multilayered magnetic junctions with...
