| Abstract | We use ab initio molecular dynamics to study the structural and electronic properties of cleaved and annealed Ge(111) surfaces. New features emerge for both structures. For the (2 × 1) it is found that even though the stable state has a π-bonded chain structure, there are two isomers with the tilt angle of the chain in opposite directions. For the c(2 × 8) we find an asymmetry in the surface unit cell, in agreement with LEED experiments that show weak quarter-order spots. This inequivalence also produces a splitting of the rest atom and adatom dangling bond, which explains recent STM experiments. | |
