Abstract
- Thin Cr films were deposited on single crystal α-Al<subscript>2</subscript>O<subscript>3</subscript>, SrTiO<subscript>3</subscript> and TiO<subscript>2</subscript> (rutile) substrates under ultrahigh vacuum conditions using molecular beam epitaxy (MBE). The growth behavior and thermal stability of the films were investigated with scanning tunneling microscopy (STM), X-ray phototelectron spectroscopy (XPS), Auger electron spectroscopy (AES), and transmission electron microscopy (TEM). Cr grew as 3D clusters on all substrates. For all three Cr/oxide systems a strong temperature dependent interfacial reaction was observed. The results suggested that these reactions depended greatly on thermodynamics and on transport properties in the oxide substrates. [ABSTRACT FROM AUTHOR]
