Reactive deposition of Ti on the Cu(001) surface saturated with chemisorbed oxygen results in the formation of an ordered ultrathin film with a slightly distorted hexagonal (quasihexagonal) unit cell. We find that, under appropriate substrate tempera

The growth mechanism, composition and structure of ultrathin films of titanium oxide deposited on the Cu(0 0 1) surface were investigated by means of XPS, LEIS, LEED and STM. Titanium oxide films were deposited on the Cu(0 0 1) surface previously sat

The alloying process of Ti deposited on Cu(0 0 1) was studied by means of XPS, LEIS, XPD and LEED intensity analysis. With the sample held at 570 K, a linear decrease of the Cu LEIS signal as a function of the amount of Ti deposited is observed in th

Submonolayers of nickel oxide were grown on the Ag(001) surface by evaporation of Ni in the presence of O2 at a pressure of 1 ? 10?6?mbar. In the early stages of deposition, two-dimensional oxide islands with a (2 ? 1) periodicity grow on Ag(001). Af

The initial growth stages of nickel deposited on Ag(0 0 1) have been investigated by LEIS, XPS, STM and XPD. Embedded atom method (EAM) calculations were performed to obtain information about the dynamics of Ni adatoms on the Ag(0 0 1) surface. Amoun

We investigate the Ir(1 1 0)-c(2 × 4)S adsorbate system using X-ray photoelectron diffraction. As proposed by a previous structure model based on a scanning tunneling microscopy experiment, we find that sulfur atoms of this superstructure enter the

The structure of a nickel oxide film 2 ML thick has been investigated by LEED intensity analysis. The NiO film was prepared by evaporating Ni in presence of O2 at a pressure in the 10 � 6 mbar range. The growth of the oxide film was followed by XPS

Exposure of the Pt3Sn(1 1 1) surface to oxygen at a pressure in the 10 � 6 mbar range at 800 K leads to the formation of a chemisorbed phase with a (4 � 4) periodicity. In previous works we investigated the structure of the (4 � 4) phase by mea
