Holey carbon films on copper (Cu) TEM grids (see Figure 2944) are usually used to support TEM specimens, e.g. nanoparticles.
In investigations of nanoparticles, to achieve high spatial resolutions (especially atomic resolution) in SEM, STEM, and TEM, very thin carbon supports have to be used. For instance, Inada, Zhu, et al. [1] employed 2-nm carbon support to obtain atomic resolution on uranium oxide nano-crystals in a Cs-corrected SEM.
