High-Resolution Carbon Coating: How much Carbon is too much?

Application Note for Leica EM ACE600 – Carbon support films are routinely used for high resolution TEM. Thickness is one of the main criteria to assess its usefulness for a particular experiment. Within that respect graphene (oxide) layers are frequently used. However, charge dissipation and mechanical stability towards high probe currents and high voltages, including long term acquisition protocols are equally important.
