Abstract :
The dynamic process of Bi line structure (BLS) has been investigated by scanning tunneling microscopy (STM) and ab initio calculation. From consecutive STM images taken after Bi deposition on the surface, we found that BLSs can be easily formed when the terraces at the front of the BLS growth contains surface defects. Using ab initio total energy calculation, we show that a dynamic ad-dimer twisting assisted process plays a crucial role to form BLS on Si(0 0 1) surface.
