Diamond is an attractive material for nanoelectronics, biological interfaces and electrical transducers. Small device dimensions are highly demanded for higher sensitivity, parallelism, remote sensing and reduced costs. Recently we have demonstrated that directly grown nanocrystalline diamond micro-channels (down to 5 um widths) are feasible and fully operational as field-effect transistors using H-terminated surface conductivity.

We prepare a thin-film heterojunction of polypyrrole (Ppy) on hydrogen-terminated diamond by electro-polymerization from solution. We combine advanced scanning techniques (AFM, KFM, micro-Raman) to characterize microscopic structural, chemical, and opto-electronic properties of such system.
