(monolayers and isolated molecular
layers) created by nanofabrication. An LB-film can consist of a
single layer or many, up to a depth of several visible-light wavelengths.
The term Langmuir-Blodgett
comes from the names of a research scientist and his assistant, Irving Langmuir and Katherine Blodgett, who discovered unique
properties of thin
films in the early 1900s. Such films exhibit various
electrochemical and photochemical properties. This has led some researchers
to pursue LB-films as a possible structure for integrated circuits (ics). Ultimately, it might be possible to construct an
LB-film memory chip in which each data bit is represented by a single molecule. Complex switching networks might be
fabricated onto multilayer LB-films chips.
