The contemporary discovery of high-temperature superconductivity in copper established oxides is an occasion of significant value not just with appreciate to the actual phenomenon itself but additionally since it certainly exhibits that good kingdom chemistry, and particularly the crystal chemistry of oxides, has an important position within the synthesis and figuring out of recent fabrics for destiny appli cations. the various papers released within the box of excessive Tc supercon ductors within the final 5 years show that the nice complexity of those fabrics necessitates a detailed collaboration among physicists and strong country chemists. This e-book is predicated to a wide volume on our adventure of the crystal chemistry of copper oxides, which we've been learning within the laboratory for greater than twelve years, however it additionally summarizes the most effects that have been got for those compounds within the final 5 years in relation to their marvelous superconducting homes. now we have eager about the struc ture, chemical bonding and nonstoichiometry of those fabrics, taking into account that redox reactions are the foremost to the optimization in their supercon ducting houses, because of the significance of the combined valence of copper and its Jahn-Teller influence. we now have additionally drawn on stories of prolonged defects through high-resolution electron microscopy and on their construction through ir radiation effects.
