摘要
通过高分辨电子显微术获得了Eu_2O_3晶体分子清洁的表面侧面原子成象,观察到了由表面附近位错滑移出表面而形成表面原子台阶的动态变化过程,同时还观察到了此种表面台阶的形核生长。
Molecularly clean surface profile images in Eu_2O_3 were obtained by HREM. The dynamicprocess of the formation of surface step by a dislocation's slipping out of the surface wasalso investigated. The nucleus of the Shape of the surface step growth was given by HREMat the same tim.e
