Abstract

Structural information on an atomic scale has been obtained for a Langmuir-Blodgett (LB) trilayer system by means of long-period x-ray standing waves. The LB trilayer of zinc and cadmium arachidate was deposited on a layered synthetic microstructure (LSM) consisting of 200 tungsten/silicon layer pairs with a 25 Å period. A 30 Å thermally induced inward collapse of the zinc atom layer that was initially located in the LB trilayer at 53 Å above the LSM surface has been observed. The mean position and width of the zinc atom layer was determined with a precision of ±0.3 Å.
