摘要
Rapid thermal annealing at 1000 degreesC of (HfO2)(1-x)(SiO2)(x) pseudobinary alloy films deposited on Si were performed in N-2 or O-2 atmospheres. The effects on the atomic transport, structure, and composition were investigated using isotopic substitution of oxygen, high-resolution transmission electron microscopy, nuclear reaction analyses, narrow nuclear reaction resonance profiling, and grazing angle x-ray reflection.
