We have developed an ultrahigh vacuum (UHV) scanning tunneling microscope (STM) cooled by superfluid 4He. This microscope is integrated with a solenoid and split-pair superconducting magnet. The STM can be operated at 300>T>4 K in a rotatable magneti

We investigate, with scanning tunneling microscopy, the Si(001) surface at low temperatures. This surface consists of asymmetric (buckled) dimers at 110 K as has been reported previously. At 20 K, however, symmetric dimers dominate the surface regard

The structure of a Si(001) surface with monatomic steps is investigated by means of scanning tunneling microscopy at 95 K and Monte Carlo simulations (MCS) at various temperatures. In particular, we pay attention to the effect of kinks at the step ed

Dynamic behavior of surface atoms on Si(001) and Ge(001) was investigated by a Variable-Temperature (VT) STM. In a range of sample temperature from 30 K to 1200 K, a variety of dynamical atomic-processes were observed on the surfaces. (1) The flip-fl

The structure of kinks at monatomic steps on Si(001) and Ge(001) is investigated by high-resolution scanning tunneling microscopy at room temperature. In addition to previously known asymmetric-dimers at edges of the ${\mathit{S}}_{\mathit{A}}$ and $

We have investigated detailed structures of monatomic steps on Ge(001) at room temperature by using high-resolution scanning tunneling microscopy. Our conclusions are different from those of Kersten et al. [Surf. Sci. 322 (1995) 1] for the same syste

We have settled a controversy that surface dimers in the Si(001) surface are intrinsically symmetric or asymmetric. Atom-resolved scanning-tunneling-microscopy (STM) images of a low-defect-density (\ensuremath{\sim}1%) surface at 144 K give definite
