Graphene electron microscope grid (silicon nitride substrate)

Overview
This product features high-quality CVD graphene transferred onto silicon nitride TEM grids, specifically designed for advanced microscopy and nanomaterial research. Utilizing catalytic chemical vapor deposition on metal substrates followed by a PMMA-assisted transfer process, these samples provide excellent electron transparency and mechanical stability for high-resolution TEM characterization. The silicon nitride substrate offers superior thermal and mechanical properties compared to conventional carbon-based TEM grids, making it ideal for demanding imaging applications.
