Attenuation Lengths of Photoelectrons in Hydrocarbon Films.

Abstract

The attenuation length, lambda, of photoelectrons with energies in the range 900-1400 eV in hydrocarbon films was measured using self-assembled monolayers of alkanethiols, HSCnH2n+1, on gold. The intensity of the photoelectron peaks from the gold substrate decreased exponentially with the chain length, with attenuation lengths of 42 A at 1402 eV, 34 A at 1151 eV, and 28 A at 940 eV. Over the narrow energy range studied, lambda was directly proportional to the kinetic energy of the photoelectrons. Keywords: Photoelectron spectroscopy; Attenuation lengths; Monomolecular films; Self assembly; Gold; Alkanethiols. (jhd)
