Tribology of Composite Au-MoS2 Films at Varying Contact Stresses (2004)
Solid-lubricant coatings for sliding electrical contact applications like slip-ring assemblies have very different requirements from typical applications like ball bearings and cutting tools: they...
Lince,J. R., Williams,R. S., Chaikin,P. M.
Transport properties of very thin (2.5 monolayer) films of Ag epitaxially grown on clean Ge(001) substrates are reported. The films consists of a monolayer coverage plus isolated three-dimensional...
Angle-Resolved Photoemission Study of AuGa2 and AuIn2 Intermetallic Compounds. (2002)
Nelson,J. G., Gignac,W. J., Kim,S., Lince,J. R., Williams,R. S.
The (001) surfaces of AuGa2 and AuIn2 intermetallic compounds were studied using synchrotron radiation excited angle-resolved photoemission. Spectra collected for photoelectron emission normal to the...
A new type of metal/semiconductor junction has been developed. Crystalline thin films of the intermetallic compound AuGa2 have been grown by molecular beam epitaxy on GaSb(001) substrates with the...
Lince, J. R., Steward, T. B., Hills, M. M., Fleischauer, P. D.
The Iron/Molybdenum Disulfide interface has been studied by high-resolution photoelectron spectroscopy using synchrotron radiation. The evolution of the MO 3d, Fe 3p, and S 2p core levels and of the...
Resonant Photoelectron Spectroscopy at the Mo 4p yields 4d Absorption Edge in MoS2. (1998)
Lince, J. R., Didziulis, S. V., Yarmoff, J. A.
A systematic study has been conducted of the resonant behavior of the valence band photoelectron spectrum of MoS2 for hv=26-70 eV, spanning the Mo 4p to 4d transition region. A broad Fano-like...
Lead Naphthenate Additive Tribochemistry in Hydrocarbon Oils (1998)
Carre, D. J., Bertrand, P. A., Lince, J. R.
There is often ambiguity concerning the antiwear mechanisms of soluble lubricant additives used in bearings. For example, the common spacecraft lubricant additive lead naphthenate is thought to be...
Friction and Wear Properties of MoS2 Thin-Film Lubricants (1998)
Fleischauer, P. D., Didziulis, S. V., Lince, J. R.
The generally agreed upon mechanism for lubrication of sliding and rolling contacts by MoS2 thin films consists of the movement of crystallites (micro or nanocrystals) over one another with friction...
Slip-ring assemblies for spacecraft, and other sliding electrical contacts, require low friction and wear, as well as low electrical resistance and noise. Most current slip-ring technologies (both...
Solid Lubrication for Spacecraft Mechanisms. (1997)
Lince, J. R., Fleischauer, P. D.
Solid lubrication is critical for many moving mechanical assemblies (MMAs) on spacecraft in applications where containment of liquids is a problem, and where extremes of temperature are involved....
