Gd-Intercalated Bilayer Graphene STM Topography Data

Scanning Tunneling Microscopy topography data supports Figure 1 of a 2026 Nanoscale publication. The dataset includes large-area and high-resolution STM measurements of epitaxial bilayer graphene on SiC before and after Gd intercalation. All data were acquired and analyzed by Shen Chen.

Use Cases

• Analyze STM topography data files (.txt) to visualize conductive nano-domains in bilayer graphene.
• Correlate scan parameters (.par files) like bias voltage and tunneling current with observed surface features.
• Reproduce the STM images from the publication using the provided WSxM ASCII topography data.
• Compare large-area and high-resolution STM measurements of graphene before and after Gd intercalation.

Strengths

• Data directly supports a peer-reviewed publication in Nanoscale (2026).
• Includes both raw topography data and associated scan parameter metadata.

Limitations

• Dataset size, row count, and specific file formats are not documented.
• Limited to STM topography data for a single figure from one publication.
• Data processing (flattening) was applied, which may affect raw signal interpretation.
