摘要

The (001) surface of nonstoichiometric wustite (Fe_(0.94)O) grown by the floating zone technique was investigated using STM, LEED and AES.Two distinctive structures, i.e., the dents arrangement and the FeO(001)-c(4x2) reconstructed structure coexist on the terrace after annealing at 1 073 K in the ultrahigh vacuum (UHV) system.On the other hand, the only dents exist after annealing at 1 273 K.The dent is the Fe vacancy pair in the rocksalt-type FeO(001)-(1 X1) matrix, which is the exposed P' phase of the defect cluster due to nonstoichiometry.
