摘要：
The degree of dimer asymmetry on the Si(001)-(2 x 1) surface as seen in high resolution scanning tunneling microscopy (STM) images has been studied in detail. It is found that the degree of dimer asymmetry can change drastically from one terrace to another. The degree of dimer asymmetry has also been studied as a function of tip material using non-magnetic W and ferromagnetic Fe tips.
