This is an abstract for a presentation given at the Seventh Foresight Conference on Molecular Nanotechnology . There will be a link from here to the full article when it is available on the web. Microcontact printing is a well-known tool for the replication of small features. The state of the art is the development of structures in dimensions of some hundreds of nanometers. A variety of problems are encountered upon approaching the 100 nm scale.
Diffusion processes appear to be responsible for the unsharpness of the replicated structures.
Using SAMs of decanethiol, the electrochemical resistivity dropped from 63.48 kOhm to 8.70 kOhm after 30 min etching. These results are confirmed by measuring the capacitance, the heterogeneous electron transfer, and by contact angle measurements. All rights reserved. Last updated 24August1999.
