Article Synopsis
- A solid grasp of nanopatterning and nanometrology is crucial for advancing nanotechnology and quantum technology fields.
- Scanning probe techniques are favored for nanoscale device fabrication due to their cost-effectiveness, but the current materials used for probes face issues like poor durability and high costs.
- The study introduces GaN nanowires as a durable semiconductor alternative, enabling sub-10 nm lithography and atomic scale patterning while maintaining cost-efficiency in scanning probe lithography and microscopy.
We report single molecule laser absorption by carbon nanotubes stamped under ultrahigh vacuum onto Si(100)2x1:H surfaces. Absorption is detected by scanning tunneling microscopy. Images are obtained with and without modulated laser excitation using lock-in amplification and a rear-illumination geometry to reduce thermal effects.
