Atomic structure of steps and defects on the clean diamond (100)-2x1 surface studied using ultrahigh vacuum scanning tunneling microscopy

摘要

We report ultrahigh vacuum scanning tunneling microscopy studies of the clean nonhydrogen-terminated diamond (100)-2x1 surface showing single- and double-layer steps that are rebonded. The main defects observed are single, multiple, and row dimer vacancies, and antiphase boundaries. Buckling of dimers is not observed, consistent with symmetric dimers.
