A new optical method for characterizing the performance of microelectromechanical systems (MEMS) is described that is significantly faster and simpler than previously described optical methods. The method uses video imaging under continuous illuminat

Magnetic transition studies have been made by measuring the electrical resistivity of thin Gd films as a function of temperature. The shift of the Curie temperature, Tc, with film thickness, d, can be characterized by a critical exponent, λ, such th

A semi-quantum-mechanical Monte Carlo simulation has been developed to model the complete angular distribution of KLL Auger electrons emitted from an Al(001) surface. Forward focusing of the Auger electrons is found in angle resolved Auger electron s

To explain the recently observed redeposition of sputtered Au, Ag, and Cu, it is shown here that low energy ions sputtered from a plane metallic surface by an obliquely incident ion beam can be returned to the surface by the electrostatic fields of t

Yields have been measured of 3 He + , 4 He + , 20 Ne + and 22 Ne + backscattered at 138° from monoenergetic (200–2300 eV) ion beams normally incident on solid and liquid Ga. The oscillatory dependence of the He + yields on reciprocal incident ion

Recent investigations have established that energy nonconserving events play a significant role in ion neutralization at solid surfaces. Such processes arise because the ionic states acquire a lifetime from the motion of the ion and its interaction w

For most noble ion-surface systems, the positions of energy-loss spectral peaks from low energy scattering are accurately predicted by the binary collision model. Deviations from the predictions of this model, however, have been observed in a number

The model of successive single binary elastic collisions used by a computer code called ARGUS is sufficiently accurate to reproduce the salient features of energy spectra that result from ion-surface scattering for the neon on nickel system down to i

Measurements and computer simulations of the energy spectra of helium ions backscattered from clean, polycrystalline tungsten at 138° have been combined to obtain estimates of the probability of survival against neutralization. For incident ion ener
