Book Description
We present a theoretical and experimental study of the spectroscopic diagnostic of hot and dense plasmas created by a laser, based on X-ray atomic emission of multicharged ions. We study gold-aluminium mixtures using a collisional-radiative code which models the different mechanism of population and depopulation of excited levels within all ionization stages from the bare ion to the neutral atom in aluminium and in gold nickel-like ions. The influence of radiative transfer on the level populations and on the observation of emission is studied. The intensive use of numerical data analysis together with powerful experimental methods allows us to interpret all the dominant structures of the gold spectrum which were previously not understood. We measure the electronic temperature and density for all kinds of the mixtures studied. We prove that the gradient of these two parameters steepens when the mean charge of the mixture increases.

Book Description
This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field.

Book Description
This volume, number 91 in the Semiconductor and Semimetals series, focuses on defects in semiconductors. Defects in semiconductors help to explain several phenomena, from diffusion to getter, and to draw theories on materials' behavior in response to electrical or mechanical fields. The volume includes chapters focusing specifically on electron and proton irradiation of silicon, point defects in zinc oxide and gallium nitride, ion implantation defects and shallow junctions in silicon and germanium, and much more. It will help support students and scientists in their experimental and theoretical paths. - Expert contributors - Reviews of the most important recent literature - Clear illustrations - A broad view, including examination of defects in different semiconductors
