Abstract
The photoelectron attenuation through layers of arachidic acid in a La ngmuir-Blodgett film has been investigated by measuring the photocurre nt. The photoelectrons were generated by the two-photon ionization of rhodamine B on a NESA glass substrate. The electron attenuation length was determined to be 4.2 nm for photoeletrons with a kinetic energy o f 0.5-1.1 eV. The value did not depend on the applied electric field o f 1.25-3.75 kV/cm.
