![]() | Liu, Feng | Influence of quantum size effects on Pb island growth and diffusion barrier oscillations | Quantum size effects are successfully exploited in manipulating the growth of (111) oriented Pb islands on Si(111) substrate with a scanning tunneling microscope. The growth dynamics and morphology displayed can be well controlled through the quantum size effects defined by the island thicknesses ... | Quantum size effects; QSE; Pb island; Diffusion barrier oscillations | 2006-08 |

![]() | Liu, Feng | Quantum size effect on adatom surface diffusion | Using scanning tunneling microscopy, we demonstrate that the nucleation density of Fe islands on the surface of nanoscale Pb films oscillates with the film thickness, providing a direct manifestation of the quantum size effect on surface diffusion. The Fe adatom diffusion barriers were derived to be... | Quantum size effect; QSE; Adatoms; Surface diffusion; Fe islands; Nanoscale metallic structures; Epitaxial growth; Pb films | 2006-12 |
