Abstract
Thin layers of perfluoropolyether lubricants Fomblin Y and Z havebeen deposited on a polycrystalline molybdenum surface andvibrational spectra have been measured by using high resolutionelectron energy loss spectroscopy. The vibrational spectra showstrong modes in the 155 meV range for Fomblin Y and Fomblin Zcharacteristic of CF3 and CF2 vibrationalmodes. Results from in situ and ex situ deposition of thelubricant on a differently prepared substrate suggest that thelubricant molecules condense on the surface forming a 300 Kmulti-layer structure.
