Kondo Cloud Measurements in Carbon Nanotube-Molybdenum Devices

Experimental data provides evidence for Kondo screening clouds in devices made from mirror-symmetric carbon nanotube arrays separated by a molybdenum strip. The dataset includes measurements of Kondo temperature plateaus at approximately 107.8 K and 15.8 K, correlating with molybdenum strip widths between 0.3 and 3.0 micrometres. Zheng Wei published this data on figshare in April 2026.

Use Cases

• Analyze the relationship between molybdenum strip width and the observed Kondo temperature plateau values.
• Validate two-spin model calculations against experimental Kondo temperature data for intra-edge and inter-edge coupling.
• Investigate the crossover behavior between the two Kondo temperature plateaus using the provided device measurements.

Strengths

• Data supports a specific physical model, with Kondo plateaus at 107.8 K and 15.8 K.
• Clear experimental parameters defined, including molybdenum strip widths from 0.3 to 3.0 micrometres.

Limitations

• Dataset is small at 180.6 KB, indicating limited scope and likely a low number of data points.
• Column names and data structure are unknown, requiring inspection of the XLSX file for analysis.
