Molecular devices formed by direct monolayer attachment to silicon

Abstract

This paper presents the results of studies of solution-based attachment of long-chain aliphatic molecules to hydrogen-terminated Si surfaces to pursue the electrical properties of organic monolayers and as a first step towards creating hybrid silicon-molecular nanoelectronic devices. The effect of differing alkane chain length on the electrical properties were measured. To investigate the quality of the organic monolayers measured in these devices, they were physically and chemically characterized with infrared spectroscopy, spectroscopic ellipsometry, and contact angle measurement.
