Electrical and Spectroscopic Characterization of Metal/Monolayer/Si Devices

November 24, 2005
Author(s)
Curt A. Richter, Christina A. Hacker, Lee J. Richter
A simple technique for vibrational spectroscopy of metal/monolayer/silicon structures is applied to study the interaction of Au, Al, and Ti with alkane monolayers, either assembled onto thin oxides or directly attached to Si. The results are correlated

Marginally Flammable Materials: Burning Velocity of Trans-Dichloroethylene

September 10, 2000
Author(s)
Gregory T. Linteris, Valeri I. Babushok
The overpressure dynamics and explosion hazard of commodity materials under full-scale conditions are often assessed through laboratory measurements of their laminar burning velocity. We present the first measurements of the flame speed of trans-1,2
