## Description

- description: Direct synthesis of thin-film carbon nanomaterials on oxide-coated
    silicon substrates provides a viable pathway for building a dense array of miniaturized
    (micron-scale) electrochemical sensors with high performance. However, material
    synthesis generally involves many parameters, making material engineering based
    on trial and error highly inefficient. Here, we report a two-pronged strategy
    for producing engineered thin-film carbon nanomaterials that have a nano-graphitic
    structure. First, we introduce a variant of the metal-induced graphitization technique
    that generates micron-scale islands of nano-graphitic carbon materials directly
    on oxide-coated silicon substrates. A novel feature of our material synthesis
    is that, through substrate engineering, the orientation of graphitic planes within
    the film aligns preferentially with the silicon substrate. This feature allows
    us to use the Raman spectroscopy for quantifying structural properties of the
    sensor surface, where the electrochemical processes occur. Second, we find phenomenological
    models for predicting the amplitudes of the redox current and the sensor capacitance
    from the material structure, quantified by Raman. Our results indicate that the
    key to achieving high-performance micro-sensors from nano-graphitic carbon is
    to increase both the density of point defects and the size of the graphitic crystallites.
    Our study offers a viable strategy for building planar electrochemical micro-sensors
    with high-performance.
