STM Analyzer

Purpose

The STM Analyzer skill provides atomic-resolution surface analysis through scanning tunneling microscopy, enabling visualization of atomic structures and measurement of local electronic properties.

Capabilities

• Atomic-resolution imaging
• STS (Scanning Tunneling Spectroscopy)
• Local density of states mapping
• Surface reconstruction analysis
• Molecular imaging
• Low-temperature operation protocols
