Mixed metal oxides Interuniversity Microelectronics Centre
A first mixed metal oxide (4) consisting of: a) a mixture consisting of 0.50 to 0.90 parts by mole Mg, 0.05 to 0.30 parts by mole Al, 0.01 to 0.20 parts by mole Sb, and 0.00 to 0.31 parts by mole of other elements, other than Mg, Al, and Sb, selected from metals and metalloids, wherein the sum of all parts by mole of Mg, Al, Sb, and the other elements, other than Mg, Al, and Sb, selected from metals and metalloids amounts to 1.00, b) oxygen, and c) less than 0.01 parts by mole of non-metallic and non-metalloid impurities, wherein the parts by mole are as measured by Rutherford Backscattering ...
