A new cluster time-of-flight secondary ion mass spectrometry (TOF-SIMS) was developed using a size-selected gas cluster ion as a projectile. Since a large gas cluster ion can generate many low-energy constituent atoms in a collision with the surfa...
Using a molecular dynamics simulation, we examine the actuation of nanodrums consisting of a single graphene sheet. The membrane of the nanodrum, which contains 190 carbon atoms, is bent by collision with a cluster consisting of 10 argon atoms. Th...

Oxidation reactions at Si(001) surfaces have been studied via real-time in situ photoemission spectroscopy with synchrotron radiation for chemical bonding states of Si and O atoms and mass spectrometry for desorption of SiO molecules with superson...
We present here a supersonic molecular beam investigation of the initial sticking probability (SO) for the O-2/Cu(410) system. Over the temperature range between 130 and 800 K adsorption occurs dissociatively and So increases up to similar to 0.7 ...

The process of sputtering by bombardment with gas cluster ions was investigated from the perspective of the kinetic energy per constituent atom (E-atom) of an incident cluster ion, which determines the threshold for the formation of craterlike def...
