Abstract
The surface structures of lead deposited on an Mo(110) surface were studied by means of reflection high-energy electron diffraction (RHEED) and scanning electron microscopy (SEM). Four kinds of surface structure were observed. Three surface structures appeared at nearly one monolayer of lead coverage at room temperature. All surface structures have large unit cells that coincide with the atomic arrangement of the molybdenum substrate. The growth modes of the Pb/Mo(110) system are the Frank–van der Merwe growth mode at room temperature and the Stranski–Krastanov growth mode at high temperatures. The epitaxial orientation relationship of the Pb/Mo(110) system is [1̄10] Pb‖[001] Mo, (111) Pb‖(110) Mo.
