MATERIALS
Chemical engineers have developed a "self-assembling" method that could allow optical devices to be made less expensively than conventional processes, which require complex etching and other techniques common in the semiconductor industry.
The method, developed at Purdue Univ., works by positioning tiny particles onto a silicon template containing precisely spaced holes that are about one one-hundredth the width of a human hair. To produce the singlelayer structure, the engineers used Langmuir-Blodgett monolayer deposition, a standard technique used in physical chemistry, primarily to create lipid membranes for research.
The template is immersed in water in a trough-like vessel ...
