Utilization of the high temperature superconductor, YBa 2 Cu 3 O 7−δ , in commercial applications is becoming increasingly feasible. Before full advantage of this material can be taken, however, the lifetime, oxygen stability and processability of

A cosubstitution of Ca2+ for Y3+and La3+ for Ba2+ in YBa2Cu3O7−δ is found to improve the corrosion resistance of this high‐ Tc superconductor. The reactivity characteristics of bulk and thin film samples of Y1−zCazBa2−yLayCu3O7−δ indicate

Effects of NH3 nitridation on the chemical and electrical properties of N2O oxides have been studied. Compared with NH3‐nitrided SiO2, NH3 nitridation does not degrade the electrical properties of N2O oxides, thus resulting in superior impurity dif

The chemical structure and composition of ultrathin N2O oxides have been investigated using angle resolved x‐ray photoelectron spectroscopy and compared to those of reoxidized NH3‐nitrided SiO2. It is found that N2O oxide shows a second nitrogen

Although it is known that some of the high‐Tc phases react rapidly with water, CO2, CO, and acids, no systematic comparison of the relative reactivities of the various cuprate superconductors is available. In this letter, x‐ray powder diffraction

Single source precursors which contain preformed gallium-nitrogen and aluminum-nitrogen bonds are being considered for the growth of gallium and aluminum nitride because of their potential for overcoming problems associated with conventional precurso
