摘要
We present recent experiments conducted with our tabletop EUV reflectometer to characterize the detailed geometry, composition, and topography of several nanostructured, polymer-based samples. The EUV measurements are performed without sample damage or any significant sample preparation. Correlative STEM measurements confirm the EUV results, but require extensive sample preparation.
