摘要：

Atomic defects were investigated on p-doped GaP(110) surfaces by scanning tunneling microscopy. The defects were identified as positively charged phosphorus vacancies and uncharged phosphorus adatoms. They are found to migrate on the phosphorus sublattice. Their motion was observed with atomic resolution and the dependence of the jump probability on the tunneling voltage was measured. The position changes of the defects were found to be induced by tip-specimen interactions.
