Epitaxial growth of fcc-Sm/Yb artificial superlattices

Yb metal deposited by a molecular-beam epitaxy technique was grown as an fcc single crystal on a NaCl substrate with an epitaxial relationship in which the Yb (100) [100] is parallel to the NaCl (100) [100]. An epitaxial Sm/Yb superlattice was successfully prepared on this Yb buffer layer at a growt...

Description
Summary:Yb metal deposited by a molecular-beam epitaxy technique was grown as an fcc single crystal on a NaCl substrate with an epitaxial relationship in which the Yb (100) [100] is parallel to the NaCl (100) [100]. An epitaxial Sm/Yb superlattice was successfully prepared on this Yb buffer layer at a growth temperature of 290 K. The Sm layers in the prepared superlattices were found to be in the fcc structure which is a new metastable phase. It was also shown that fcc-Sm can be epitaxially grown on the fcc-Yb layer up to a thickness of 3000 Å.
