Elastic and adhesive properties of alkanethiol self-assembled monolayers on gold

March 30, 2009
Author(s)
Frank W. DelRio, Cherno Jaye, Daniel A. Fischer, Robert F. Cook
Elastic and adhesive properties of alkanethiol (CH3(CH2)n 1SH) self-assembled monolayers on gold are investigated by atomic force microscopy and correlated with surface structure via near edge x-ray absorption fine structure spectroscopy. As the chain

Terrence J. Udovic, Jeremy Cook, Alexander Skripov, Reinhard Hempelmann, Andrey Rempel, Aleksandr Gusev
In order to study the mechanism and parameters of H jump motion in the nonstoichiometric Nb carbides, we have performed quasielastic neutron scattering (QENS) measurements for NbC(0.71)H(0.28) over the temperature range 11- 475 K. Our results indicate that

Test Chip to Evaluate Measurement Methods for Small Capacitances

March 30, 2009
Author(s)
Joseph J. Kopanski, Muhammad Y. Afridi, Chong Jiang, Curt A. Richter
We designed and fabricated a test chip to help us evaluate the performance of new approaches to measurement of small capacitances (femto-Farads to atto-Farads range). The test chip consists of an array of metal-oxide-semiconductor capacitors, metal
