Shudder in continuously slipping wet clutch (CSWC) systems is an instability that manifests itself as a vibration of the automobile's drive train. Dynamometer experiments imply that the shudder is connected to degradation of the frictional properties

We have measured Coulomb-blockade effects in a two-tunnel-junction structure formed with a scanning-tunneling-microscope (STM) tip and samples composed of gold particles deposited onto a partially oxidized aluminum-base-layer film. Clear topographic

A simple theory of the effect of monatomic steps on the local density of surface states and on the conductance of a scanning tunneling microscope (STM) has been developed. This theory is based upon reflection and transmission amplitudes for surface e

The authors show that the I-V characteristics measured at 4 K of single tunnel junctions between the tip of a scanning tunneling microscope and a metallic sample are sensitive to the materials used. The superconducting energy gap of lead is observed

We describe a method for measurement of the local density of states on metals with the scanning tunneling microscope and apply it to the study of the sp‐gap surface state on Au(111). Local surface state peak intensity changes are found to correlate

We have measured reproducible tunneling spectra on ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ (${\mathit{T}}_{\mathit{c}}$\ensuremath{\sim}85 K) thin films (thickness \ensuremath{\sim}2 \ensuremath{\mu}m) with a cryogenic scanning tunn

A miniature capacitive force sensor which fits in the sample position of an atomic force microscope (AFM) has been used to calibrate the force applied by the scanning tip during nanohardness measurements. The sensor is simple, physically robust, and

When scanning steeply sloped features which are near micron size or taller, scanning tunneling microscopes with conventional feedback control loops exhibit slower response on downhill slopes than on uphill slopes. This effect is caused by the exponen

The effects of boundary lubricants and metallic oxides upon the interaction between two asperities is central to the tribological behavior of metal-metal systems. We have used an Atomic Force Microscope to measure tribological properties of micron-sc
