Initial stages of FeO growth on Ru(0001)

Initial stages of FeO growth on Ru(0001).

We study how FeO wüstite films on Ru(0001) grow by oxygen-assisted molecular beam epitaxy at elevated temperatures (800–900 K). The nucleation and growth of FeO islands are observed in real time by low-energy electron microscopy (LEEM). When the growth is performed in an oxygen pressure of 10(−6) Torr, the islands are of bilayer thickness (Fe–O–Fe–O). In contrast, under a pressure of 10(−8) Tor...

Initial stages of the growth of CaF2 on Cu(111) visualized by STM

The epitaxial growth of insulators on semiconductor surfaces is a topic that has attracted widespread interest in recent years. In particular, a strong effort has been devoted to study the growth of CaF 2 on Si(111) and (100) surfaces [1] because of the potential interest for novel Si-based quantum effect devices, such as Resonant Tunnelling Diodes operating at 300 K [2]. Much less is known con...

Initial stages of benzotriazole adsorption on the Cu(111) surface.

Benzotriazole (BTAH) has been used as a copper corrosion inhibitor since the 1950s; however, the molecular level detail of how inhibition occurs remains a matter of debate. The onset of BTAH adsorption on a Cu(111) single crystal was investigated via scanning tunnelling microscopy (STM), vibrational spectroscopy (RAIRS) and supporting DFT modelling. BTAH adsorbs as anionic (BTA(-)), CuBTA is a ...
