A nickel oxide that is co-doped with a first alkali metal dopant and a second metal dopant may be used, for example, to form a dielectric material in an electronic device. The dielectric material may be used, for example, in a capacitor. The second metal dopant of the nickel oxide may be, for example, tin, antimony, indium, tungsten, iridium, scandium, gallium, vanadium, chromium, gold, yttrium, lanthanum, ruthenium, rhodium, molybdenum or niobium.

Co-doped nickel oxide

Lead-free solder alloys based on a Sn&mdash;Ag&mdash;Mg system are disclosed. The alloy compositions have a melting temperature close to 183&deg; C. and a similar surface tension to that of Sn&mdash;Pb solder, and can thus be a readily substituted for conventional Sn&mdash;Pb solders. P may be added to the alloy compositions to reduce its tendency of oxidation.
