Controlled deposition of size-selected silver nanoclusters

Klaus Kern, Harald Brune, Wolfgang Harbich, René Monot

Variable-temperature scanning tunneling microscopy was used to study the effect of kinetic cluster energy and rare-gas buffer layers on the deposition process of size-selected silver nanoclusters on a platinum(111) surface. Clusters with impact energies of ...

The fate of mass selected silver clusters deposited on Pd(100)

Wolfgang Harbich, René Monot

We present a new experiment to monitor ionized atom and mass selected cluster depositions in real time using specular reflected thermal helium scattering. Monomer Ag ions with an incident kinetic energy of E/sub dep/=20 eV and E/sub dep/=95 eV create surfa ...

Surface diffusion of Ag on Pd(100) measured with specular helium scattering

Wolfgang Harbich, René Monot

We present a new method to determine surface diffusion constants using specular reflected thermal helium scattering. The specular reflected helium intensity is recorded in real time as a function of surface coverage of the adsorbate and surface temperature ...

Neighbor driven mobility of silver adatoms on Pd(100) measured by thermal helium scattering

Wolfgang Harbich, René Monot

Thermal helium scattering is used to characterize the deposition of silver atoms on Pd (100) in the coverage range 0 to 10% of a monolayer, at surface temperature between 80 and 160 K, the latter being the threshold of adatom mobility. The attenuation of t ...

Chemisorption and macroscopic diffusion of NO on Pt(111)

Wolfgang Harbich, René Monot

Thermal energy helium scattering is used to measure the isothermal desorption of NO from Pt(111) in the temperature range 343-383 K. Taking into account the vibrational degrees of freedom to calculate the residence time of the molecules, the energy of adso ...

Mass-selected deposition of Ag 7 on Pd(100). Evidence for implantation and strong fragmentation

Wolfgang Harbich, René Monot

We present a new experiment which is able to monitor mass-selected cluster depositions in red time using specular reflected thermal helium scattering. Ag/sub 7//sup +/ with an incident energy of 2.86 and of 13.6 eV/atom is deposited on Pd(100) at different ...

Measurement of macroscopic diffusion of CO on Pt(111) by thermal helium scattering

Wolfgang Harbich, René Monot

A new method to measure the diffusion of adsorbed molecules over macroscopic distance on single crystal surfaces is presented and demonstrated with the system CO on Pt(111). A controlled coverage of molecules, typically of the order of 0.01 monolayer, is d ...
