原子間力顕微鏡によるMgO単結晶表面の観察

抄録

The (100), (110) and (111) planes of MgO were observed at an atomic scale using an atomic force microscope. It was identified that the surface structures were different from the bulk ones and that the surface defects existed on each surface. It can be suggested that the surface free energy and the polarization play an important role in the alteration of the surface structures. It can be considered that all the bright spots in the AFM images correspond to the positions of the oxygen atom in the case of the MgO surface.
