The adsorption and decomposition of C2H4 on GaAs(100) and Al-GaAs(100) has been studied using TDS, AES and HREELS techniques. Ethene is adsorbed non-dissociatively between 150 and 650 K on both surfaces. On heating to 650 K approximately 60% of the a

We have investigated the photon stimulated desorption of ions from physisorbed layers of CO and ${\mathrm{O}}_{2}$ on graphite using VUV synchrotron radiation in the range of 13 to 35 eV. In both systems we find a significant enhancement in the monol

We have studied photon stimulated ion desorption from O 2 physisorbed on graphite, using synchrotron radiation in the energy range 16–40 eV. Ar spacer layers were employed in order to distinguish between direct and indirect (photoelectron driven) d

We have investigated photon stimulated desorption (PSD) and electron stimulated desorption (ESD) from CO films physisorbed on graphite and Pt(1 1 1) at monolayer coverages, with photon and electron energies in the range 13–35 and 0–70 eV, respect

The thermal reactions of Cl2 with the GaAs(100) surface were studied using XPS, LEED and thermal desorption spectroscopy. Chlorine uptake at 175 K is initially very rapid, but an extensive corrosion phase is not formed. Five thermal desorption featur

We report a surface photochemistry study using ultrafast pulses of vacuum ultraviolet (vuv) light for excitation. Tunable vuv radiation (10-38 eV) is produced via high harmonic generation. We have studied the model systemof physisorbed O 2 on graphit

We report here the development of a tunable vacuum ultraviolet light source, providing subpicosecond pulses over the wavelength range from 114 (∼11 eV) to 32 nm (∼39 eV), designed for surface science experiments. The source is based on high order

THE diminishing reserves of petroleum oil have focused attention on the possibility of making more efficient use of natural gas, reserves of which are at present considerably under-utilized. Methane is commonly used as a fuel, but it is also the star

A comparative study of photodesorption from physisorbed oxygen layers on (highly oriented pyrolytic) graphite and Pt(111) surfaces has been carried out using continuously tuneable synchrotron radiation in the energy range 13 - 35 eV. The photodesorpt
