Abstract

We present the results of studies of solution-based attachment of long-chain aliphatic molecules to hydrogen-terminated Si surfaces formed to pursue the electrical properties of organic monolayers and as a first step towards creating hybrid silicon-molecular nanoelectronic devices. Direct attachment of organic molecules to the silicon surface is of increasing importance for emerging molecular electronics applications as devices incorporating molecules chemically bonded to silicon are amenable to integration with existing Si processing techniques. Current-voltage and capacitance-voltage measurements were obtained from a metal-organic-silicon test structure fabricated by post-monolayer metal deposition. The effect of differing alkane chain length on the electrical properties was 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 measurements.
